What do thermal causes and power causes refer to?

You're asking about a three-lap circulation.

Right? Hope mine is helpful to you!

Heat is caused by the rise or sink of the air flow due to the local hot and cold reasons. The equatorial low-pressure zone is formed by the expansion and rise of the equatorial near-surface air by heating, and the polar high-pressure zone is formed by the contraction and sinking of the polar near-surface air when it is cold. Therefore, the equatorial low-pressure zone and the polar high-pressure zone are thermogenally formed.

and then the low-latitude circulation and high-latitude.

Gyrospheres are formed by thermal causes.

Air is forced to rise or sink due to other reasons, which is a motive cause. Subtropical high-pressure belt.

It is formed because the upper air flow is forced to sink, and the subpolar low pressure zone is formed because of the formation of the polar front and the air flow is forced to rise. Therefore, the subtropical high pressure belt and the subpolar low pressure belt are formed by dynamic causes. Furthermore, the mid-latitude circulation is formed by dynamic reasons.

1. The formation of the equatorial low-pressure belt is due to the fact that the ground is heated a lot, and the air convection rises, forming a low-pressure belt; The formation of the polar high-pressure belt is due to the cold ground and the occurrence of downdrafts, forming the high-pressure belt. This process of forming a pressure zone due to the overheating and overcooling of the ground belongs to the thermal factor.

2. The formation of the subtropical high-pressure belt is due to the accumulation of air at high altitude, which causes the airflow to sink and form the high-pressure belt; The formation of the subpolar low-pressure zone is due to the convergence of cold and warm air on the ground, causing the warm air to rise and form the low-pressure zone. This process of forming a barometric pressure zone is a dynamic factor.

Summary. Hello, the urban heating system consists of three parts: heat source, heat network and heat user. The urban heating system is a heating network that uses centralized heat sources to produce or live heat energy to heat users through heating pipe networks and other facilities.

A heat source is a boiler room or thermal power plant that produces and prepares a heat medium with certain parameters (temperature, pressure). The heat network is an outdoor heating pipeline system that transports heat media, is the link between the heat source and the heat user, and plays the role of transporting and distributing the heat source. It is directly delivered to the heat user through the heat network, and the heat user can use or consume heat energy for indoor heating, ventilation and air conditioning, hot water** and heat systems for production processes.

Urban central heating is one of the urban infrastructures, which has comprehensive economic, environmental and social benefits of saving energy, reducing pollution, conducive to production and convenient life. The policy and principle of urban heating to implement central heating is to adhere to local conditions, open heat sources, advanced technology, and economic reasonableness.

How is the heat generated by a thermal power company.

Relatively good.

How does the heat come from? Electricity? Burning coal? Power plant waste heat?

It mainly burns gas and electric boilers, burns coal in some areas, and uses waste heat from power plants near power plants.

There's no shortage of energy, it's just central heating, right? <>

Yes, it also provides convenience for normal production and life.

Understood, thank you <>

Chemical thermodynamics is a sub-discipline of physical chemistry and thermodynamics, which mainly studies the energy changes accompanied by the physical and chemical changes of the material system under various conditions, so as to make accurate judgments about the direction and degree of chemical reactions.

Chemical kinetics (chemical

kinetics is a sub-discipline of physical chemistry that studies the rate and reaction mechanism of chemical reaction processes, and its research object is the non-equilibrium dynamic system of material properties with time. Time is an important variable in chemical kinetics.

The theory of the structure of matter talks about the structure of matter, and it includes matter (inorganic, organic...).What particles are made of, how do these particles make up the substance, why is it the way it is, what properties of the substance are determined by such composition, etc.

If you are going to engage in inorganic synthesis :

First of all, you have to know the possibility of using certain raw materials to synthesize the product you need under certain conditions - chemical thermodynamics. If thermodynamically, the raw material cannot undergo a chemical reaction to produce the desired product (under certain conditions), then you don't need to think about it any further!

If thermodynamically it is judged that the reaction can occur, then the remaining question is how to make the reaction occur under the conditions that can be achieved by production. For example, through calculations, thermodynamically, it is determined that hydrogen can be combined with oxygen to produce water at room temperature, but if we just mix hydrogen with oxygen at room temperature, then it is difficult to see a single drop of water in a million years.

Why? Thermodynamic possibility is not the same as reality! Thermodynamically it says that a reaction can occur, but it just says that the occurrence of this reaction does not violate the law of conservation of energy!

As for the speed of the reaction, thermodynamics cannot be predicted. It depends on chemical kinetics. If we put a little pt in the mixture of hydrogen and oxygen, then at room temperature, hydrogen and oxygen will react immediately to form water.

That's what kinetics is about – how the reaction goes through a microscopic process.

The structure of matter determines the thermodynamic and kinetic properties of matter. Don't forget the most basic idea of chemistry that I learned in junior high school chemistry - the composition and structure of matter determine the properties of matter.

This major is divided into different directions such as boilers, steam turbines, and internal combustion engines, and employment is also different, and the treatment, the degree of hard work, and whether it is necessary to work shifts and travel are also very different. I hope you think it through.

It is the boiler, steam turbine and other specialties of thermal power plants.

Hot spot power actually refers to the conversion of heat into kinetic energy.

For example, steam, boilers, etc., are all applications of thermal power.

Thermal power system, its central steam turbine and boiler are more important, thermal power engineering mainly transports large power stations, boiler plants, as well as beer, pharmaceuticals and other industries that need to convert thermal energy into kinetic energy or heat energy into high-temperature steam.

The major of thermal energy and power engineering cultivates senior engineering and technical talents who have basic knowledge of thermal energy engineering, heat transfer, fluid mechanics, power machinery, power engineering, etc., and can be engaged in the design, manufacturing, operation, management, experimental research and installation, development, and marketing of power engineering (such as thermal power plant engineering, hydropower power engineering, refrigeration and cryogenic engineering, and air conditioning engineering) of power machinery (such as heat engine, fluid machinery, and hydraulic machinery) in various sectors of the national economy. Mainly learn the basic theories of power engineering and engineering thermophysics, learn various theories and technologies of energy conversion and effective utilization, and receive basic training from modern power engineers; It has the basic ability to design, operate and conduct experimental research on power machinery and thermal equipment.

Heat is caused by the rise or sink of the air flow due to the local hot and cold reasons. The equatorial low-pressure zone is formed by the expansion and rise of the equatorial near-surface air due to heating, and the polar high-pressure zone is formed by the contraction and sinking of the polar near-surface air when it is cold. Therefore, the equatorial low-pressure zone and the polar high-pressure zone are thermogenally formed.

In addition, the low-latitude circulation and the high-latitude circulation are both formed by thermal causes.

Air is forced to rise or sink due to other reasons, which is a motive cause. The subtropical high pressure zone is formed by the forced sinking of the high air current, and the subtropical low pressure belt is formed by the formation of the polar front and the forced upward movement of the air flow. Therefore, the subtropical high pressure belt and the subpolar low pressure belt are formed by dynamic causes.

Furthermore, the mid-latitude circulation is formed by dynamic reasons.

The irregular motion of a large number of molecules inside an object is known as thermal motion. The energy possessed by the thermal motion of the land is called thermal energy, which is the internal energy of the object.

The heat energy is related to the grinding temperature of the object, the higher the temperature, the faster the molecule moves, and the greater the heat energy it has.

Solution: 1) All objects have internal energy, and the magnitude of internal energy is related to mass, temperature, and state.

2) The internal energy of the object changes, which may be manifested in the temperature change of the object, or it may be the change of state.

3) There are two ways to change the internal energy of an object: work done and heat transfer.

a. The object emits heat, and the temperature may not change, for example: the crystal is exothermic but the temperature does not change during the solidification process, which does not meet the topic;

b. The increase of the thermal energy [internal energy] of the object may be due to the work done by the outside world on the object, which does not conform to the topic;

c. When the temperature of the object increases, its blind heat energy [internal energy] will definitely increase, which is in line with the topic;

d. Different objects with the same temperature may not have the same thermal energy [internal energy], which does not conform to the topic;

Therefore, C <> is chosen

Comments: The test point of this question: The relationship between temperature, heat and internal energy

Test Center Comments: To understand the relationship between temperature, heat and internal energy Know that the object absorbs heat and the temperature increases, and the internal energy increases; The object is exothermic, the temperature decreases, and the internal energy decreases At the same time, it is necessary to master two ways to change the internal energy of the object: work done and heat transfer.

The horizontal pressure gradient force is the direct cause of the wind generation.

The horizontal pressure gradient force is generated by the presence of a difference in air pressure in the horizontal direction. As long as there is a pressure difference in the horizontal direction, a horizontal air pressure gradient force is generated, and wind is generated.

The difference in air pressure in the horizontal direction is caused by the difference in air pressure in two adjacent places. The high pressure and low pressure generation have thermal factors and dynamic factors. Thermal factors produce thermal low pressure (equatorial low pressure) and cold high pressure (e.g., polar high pressure); Kinetic factors generate thermal high pressures (e.g., subtropical highs.

and cold low pressure (e.g., subpolar low pressure).

First, you can search in the encyclopedia. The following encyclopedia explains thermodynamics: thermodynamics is a discipline that studies the thermal motion properties of matter and its laws from a macroscopic perspective.

It belongs to the branch of physics, and it and statistical physics constitute the macro and micro aspects of thermal theory, respectively.

Thermodynamics is mainly the study of the thermal properties of matter from the point of view of energy conversion, which suggests the macroscopic laws that energy follows when converting from one form to another, and summarizes the thermal theory obtained by summarizing the macroscopic phenomena of matter. Thermodynamics does not investigate the microstructure of matter composed of a large number of microscopic particles, but only deals with the thermal phenomena that the system as a whole and the basic laws that must be followed for their change and development. It is content to describe and determine the state of the system with a few macroscopic state quantities that can be directly felt and observed, such as temperature, pressure, volume, concentration, etc.

Through a large number of observations and experiments on thermal phenomena in practice, it is found that there is a relationship between macroscopic state quantities, and their changes are mutually restrictive. In addition to the properties of matter, the constraint must also follow some basic thermal laws that are applicable to any substance-liquid residue, such as the zero law of thermodynamics, the first law of thermodynamics, the second law of thermodynamics, and the third law of thermodynamics. Thermodynamics is based on the above basic laws obtained from experimental observations, and the application of mathematical methods and logical deduction to obtain the relationship between various macroscopic properties of matter and the direction and limit of macroscopic physical processes, so it belongs to the phenomenological theory, and the conclusions drawn from it have a high degree of reliability and universality.

Second, the explanation of thermal force: the force that does work produced by heat energy. For example, the steam engine and the steam train of the past. It is converted into kinetic energy by heat and formed a force that can be utilized.

The interaction between the thermal system and the outside world includes: ().

a.Heat exchange.

b.Material exchange.

c.Power exchange.

d.Momentum exchange.

Correct answer to the line of rock divination: file spike hot jujube amount exchange; Material exchange. Power exchange.
