What would happen to our lives if there was no energy in nature?

NO ENERGY ...

For example, without light, the world is dark, plants no longer grow, and animals are starving to death.

The root of most of the energy on the earth is light energy, without which human beings cannot survive.

The water vapor is not evaporating, there is no wind, there are no clouds, rainfall is no longer forming, and rivers are not flowing.

The only remaining oil mines can provide us with a living situation for a period of time, after which humanity will go to war for resources.

However, there was no winner in the war, as the victorious side only lasted a few weeks.

The earth will fall silent.

Expand on it yourself ...

Without energy, there is no life, does this need to be asked? Tell your teacher this.

Any object needs energy to work, and without energy, there would be no movement and change in nature, and there would be no life.

Energy is a measure of the degree of change in the spatial and temporal distribution of mass, which is used to represent the ability of a physical system to do work. Modern physics has clarified the quantitative relationship between mass and energy, that is, Einstein's mass-energy relation: e=mc.

The unit of energy is the same as the unit of work and is joules (j) in the International System of Units. In nutrition, in addition to using joules (j) as the unit of energy, calories (cal) are sometimes used as the unit of energy, and 1 calorie is approximately equal to joules.

In the fields of atomic physics, nuclear physics, particle physics, etc., electron volts (EV) are also used as the unit of energy, 1 electron volt = , 18 10 19 joules. In the field of theoretical physics, there are also ergs (erg) as the unit of energy, 1 erg = 10 7 joules.

Energy exists in many different forms. According to the classification of different forms of motion of matter, energy can be divided into nuclear energy, mechanical energy, chemical energy, internal energy (thermal energy), electrical energy, radiation energy, light energy, biological energy, etc. These different forms of energy can be converted into each other through physical effects or chemical reactions.

Various fields also possess energy.

In nutrition, energy refers to the chemical energy (biomass energy) contained in food that can be absorbed by the human body, and the energy in eating blind things can sometimes be called calories, and the energy consumed by a normal adult per day is about joules (8400 kJ, NRV nutrient reference value).

Natural Gas, Nuclear, Wind, Ocean Thermogen, Hydro, Gasoline, Solar, Electricity, Coal, Hydrogen Energy, Gas, Steam, Diesel, Petroleum, Geothermal, Tidal Energy, Biomass Energy.

There are so many forms! There are bioenergetic, chemical, mineral energy, such as: oil, coal, natural gas!

There are also wind energy, water energy, atomic energy, and so on, ......

Hello, the first thing to understand is the "law of conservation of mass (or energy)" (first of all, I am not a professional, just to express my own opinion) 1. Generally speaking, energy is not generated out of thin air, nor is it reduced, but is transferred from one substance to another, or transformed into different forms of energy as the transformation process of energy, which is the law of conservation of energy. 2. Regardless of the physical change of the substance, the chemical change ......The mass of both the product and the pre-reaction is equal, which is the law of conservation of mass. 3. Energy and mass are not static, and conservation is only relative and within a certain range.

When matter reaches certain conditions, even mass will become energy, and energy will be converted into mass (in my opinion: the mass of the sun has actually been decreasing, and it is converted into energy radiating around) The conversion relationship between mass and energy is: e mc2 (e energy, m mass, c2 the square of the speed of light) Regarding the form in which energy exists:

You can first think of the structure of particles from large to small: objects, molecules, atoms, various nucleons (particles in the nucleus, many kinds of examples, such as neutrons, protons), electrons, ......Basically every particle has one or more forms of energy in its own way: such as:

Object: Mechanical energy (including kinetic energy, potential energy, etc.) Molecule: Molecular potential energy (internal energy, mechanical waves......Atom:

Chemical energy, electrical energy (interionic) Nucleon: nuclear energy, electromagnetic waves, ......Electronics: electrical energy, electromagnetic waves (radiation, etc.) ....There are also some special ones such as:

Light energy Mechanical wave energy + electromagnetic wave energy These are all summarized by myself without much scientific investigation ......If you want to be more standard, you can only consult the relevant experts.

Energy is neither destroyed nor created out of thin air, it is only transformed from one form to another, or transferred from one object to another, and in the process of transformation or transfer, its total amount remains the same This is the law of conservation of energy It is one of the most universal and important fundamental laws of nature Therefore a is correct; However, in the actual process, after the slip energy is converted, the available energy will only decrease, and will not increase Therefore, we must save and effectively use the energy to make the old In the spontaneous process of nature, the transformation and transfer of energy is directional, and all macroscopic processes related to thermal phenomena are directional. Therefore, not all energy conversion is reversible, so b and c are correct and d are wrong;

Therefore, choose D

Who told you that humans only discovered electricity?

There are many types of energy, and there are different ways to classify them according to different criteria.

Personally, I think the best classification method is to divide it into mechanical energy, internal energy, electrical energy, chemical energy, atomic energy, etc

Mechanical energy: the energy that does mechanical motion, such as kinetic energy, gravitational potential energy, and even wind energyInternal energy: the energy of molecules doing thermal motion, and the "heat" felt in reality is one of the manifestations of internal energy

Needless to say, this is the energetic chemical energy of the directional movement of the charge: the energy produced when the chemical reaction of a substance occurs, such as the chemical reaction in a dry battery, but this energy is generally immediately converted into other energy, such as the conversion into electrical energy in a dry battery, the conversion of combustion into internal energy, light energy, and so on.

Atomic energy: The energy of the interaction between the components inside the atom, such as nuclear energy, etc.

There are too many forms of energy, mechanical energy, gravitational potential energy, electric potential energy. There are too many of them, but so many forms of energy are essentially the effects of interaction.

There are mainly solar, wind, tidal, geothermal and so on.
