Most of the energy that is converted into is lost in the form of internal energy

Energy is neither created nor disappeared out of thin air, it can only be transformed from one form to another, or from one object to another, and its total amount remains unchanged in the process of transformation or transfer. The law of conservation of energy is widely accepted today, but it has not been rigorously proven.

1) Different forms of energy in nature correspond to different forms of motion: the motion of objects has mechanical energy, the motion of molecules has internal energy, the motion of electric charges has electrical energy, the motion inside the nucleus of an atom has atomic energy, and so on.

2) Different forms of energy can be converted into each other: "Frictional heat generation is the conversion of mechanical energy into internal energy by overcoming friction and doing work; When the water in the kettle boils, the water vapor does work on the lid of the kettle to lift the lid up, indicating that the internal energy is converted into mechanical energy; The electric current does work through the heating wire, which converts electrical energy into internal energy, and so on." These examples illustrate the process by which different forms of energy can be converted into each other and by doing work.

3) If the energy of a certain form decreases, there must be an increase in the energy of other forms, and the amount of decrease and increase must be equal The decrease in the energy of a certain object must have an increase in the energy of other objects, and the amount of decrease and increase must be equal.

Specific expressions of conservation of energy:

Conservative mechanical system: In the case of only conservative force doing work, the energy of the system is expressed as mechanical energy (kinetic energy and potential energy), and the conservation of energy is specifically expressed as the law of conservation of mechanical energy.

Thermodynamic system: energy is expressed as internal energy, heat and work, and the expression form of conservation of energy is the first law of thermodynamics.

Relativistic mechanics: In the theory of relativity, mass and energy can be transformed into each other. Taking into account the change in energy caused by the change in mass, the law of conservation of energy still holds. Historically, the law of conservation of energy in this case has also been called the law of conservation of mass and energy.

The corollary of the second law of thermodynamics.

Summary. Energy is neither created nor disappeared out of thin air, it simply transforms from one form to another, or from one object to another, while the total amount of energy remains the same.

Energy is neither created out of thin air nor dissipated out of thin air, it is only transformed from one form to another, or the former is transferred from one object to another, while the total amount of energy remains the same.

This is the law of conservation of energy.

The law of conservation of energy is one of the universal fundamental laws of nature. It is generally stated that energy is neither created nor disappeared out of thin air, it only changes from one form to another, or from one object to another, while the total amount of energy remains the same.

It can also be expressed as follows: the total energy of a system can only be changed by the amount of energy transmitted to or from the macro. The total energy is the sum of the mechanical energy, internal energy (thermal energy) of the system, and any form of energy other than mechanical energy and internal energy.

If a system is in an isolated environment, it is not possible for energy or mass to pass in or out of the system. In this case, the law of conservation of energy is expressed as: "The total energy of an isolated system remains constant." ””

Analysis: Energy can be converted into each other, in fact, matter and energy can also be converted into each other.

The various energies we call such as light, electricity, kinetic, thermal, nuclear, solar, biomass, etc., are actually artificially divided. They can transform each other in a variety of ways. For example, heat energy can be converted into kinetic energy by a steam engine, kinetic energy can be converted into electricity by a generator, electrical energy can be converted into light energy through a light bulb, and light energy can be converted into heat energy through a bath bomb.

That's why there is a saying about the "law of conservation of energy". There is no energy in nature out of thin air, which also confirms that a "perpetual motion machine" is impossible. If you want to ask where the energy came from at the beginning, I think it should be the universe 20 billion years ago.

Matter can be converted into energy by fusion or fission, and the formula is energy = mass (the square of the speed of light).

Energy is generated by force, and the source of power in the universe is electromagnetic force and gravitational force. At present, what the scientific community wants to solve is to unify the electromagnetic force and the gravitational force into one force, which is called the "grand unified theory". Einstein devoted himself to this research in his later years, and the landlord can take a look at Stephen Hawking's book "A Brief History of Time".

It is recommended that after learning calculus, you will have different feelings.

Why is matter so easy to convert into energy and energy so hard to convert into matter? What do you know about this?

Some people say that Einstein's special theory of relativity explains that energy and mass can be converted into each other, saying that energy and mass are essentially the same thing.

Dialectical materialism holds that matter determines consciousness, but consciousness has a counter-effect on matter. This reaction can only be that consciousness can change matter, or reorganize matter, by the action of force, but it can never create matter.

The high-energy particle accelerator hits new particles, which is a collision and not a manufacture. Is it possible to knock out a large stone out of a small stone, is that a manufactured substance? High-energy particle accelerators, that's just a tool for making high capabilities.

Force can discover new substances, or reorganize new substances, but never make new substances.

Some people say that solar photosynthesis is the conversion of energy into mass, which is again misleading. Photons are essentially particles of matter, and even light energy is a force that can only push matter, change or reorganize matter. The essence of photosynthesis is recombinant matter, and it is by no means a new substance that is made.

It is also said that electrons outside an atom produce photons when they transition. Aren't electrons and photons all particles of matter? Particles will transform each other under the energy of different forces, and there will be changes in aggregation, dispersion, increase and decrease under different forces.

There are also people who say that the matter in the universe is produced by the energy of the universe, and it is energy that produces matter. The infinitesimal singularity is big**, just a hypothesis of Einstein, whether it is correct or not, let's not say for the time being.

First of all, we need to understand what is the nature of energy? Whether it is high-energy or low-energy nuclear energy, singularity and large energy, the essence of all energy is force. Force can only push, move, aggregate, scatter, change, recombine, but never create creation.

Only when you understand this truth can you know that energy and mass are not the same thing. Energy and mass cannot be converted into each other, but can only be mass to produce energy, and energy cannot produce mass.

Hope mine can help you.

This is because matter is made up of some small molecules, so it can be converted into energy, but energy is fixed, so it cannot be converted into matter.

Because the two are not working on each other. My understanding is that matter can provide energy, and matter can be transformed into energy, but energy cannot be transformed into matter, and energy is a virtual thing, which cannot be transformed into matter, but can only be transformed into another virtual thing.

This is because there is a conservation between matter and energy, and matter can be easily converted into energy, but energy needs to go through many steps to convert into matter, so it is difficult for energy to be converted into matter.

There is still a lot to understand, if these substances want to be converted into substances, they need to waste a lot of energy, for example, they can be burned, and in the process of combustion, a lot of things need to be consumed.

Because energy needs to consume more energy than the energy itself in the process of converting into matter, it is impossible to complete this phenomenon. The conversion of matter into energy is very common in real life, but the conversion of energy into matter has not been encountered in life at present.

Hello, the adverse effects of energy conversion on human production and life are mainly in the following aspects: 1Energy consumption:

Energy conversion requires the consumption of a large amount of energy, such as fossil fuels, nuclear energy, etc., and the acquisition and use of these energy sources will produce a large amount of pollution and environmental damage, such as climate change, air pollution, water pollution, etc., which will adversely affect human production and life. 2.Waste of resources:

The energy conversion process will produce a large amount of by-products such as heat, exhaust gas, and wastewater, which will cause pollution to the environment and waste a lot of resources. 3.Health Issues:

The by-products such as exhaust gas and wastewater produced by energy conversion contain a large number of harmful substances, such as carbon dioxide, sulfur dioxide, nitrogen oxides, etc., which will adversely affect human health, such as respiratory diseases, ** diseases, etc. 4.Security Issues:

Accidents such as leakage may occur in the process of energy conversion, which will pose a serious threat to human production and life.

The energy transition may have some adverse effects on human production and life, but there are also many positive aspects. Here are some common influencing factors:

Environmental impact: Certain energy conversion processes may have a negative impact on the environment. For example, burning fossil fuels releases large amounts of greenhouse gases, contributing to climate change and air pollution.

Some energy transition methods may also have adverse effects on water resources, soils and biodiversity.

Health Impacts: Certain energy conversion processes may cause harm to human health. For example, burning fossil fuels produces harmful particulate matter and air pollutants that negatively affect the respiratory and cardiovascular systems.

Nuclear energy conversion involves radiation risks that can lead to health problems if not properly handled and managed.

Economic impact: The cost and efficiency of the energy transition have an impact on economic development and human life. Some energy switching methods may require significant investment and resources, which can increase energy costs.

In addition, over-reliance on specific energy sources** may make the economy more sensitive to energy** fluctuations.

Resource sustainability: Some energy conversion methods rely on finite resources, such as oil, natural gas, and coal. Over-reliance on these resources can lead to resource shortages and instability.

Therefore, the development of renewable energy sources and energy efficiency are essential to secure the energy of the future**.

However, there are also many positive effects of the energy transition:

Clean energy and environmental protection: Switching to renewable and clean energy sources can help reduce greenhouse gas emissions and environmental pollution, and protect ecosystems and human health.

Job creation: The shift to renewable energy and the development of new energy technologies can create new jobs and promote economic growth and sustainable development.

Technological innovation and competitiveness: The energy transition has driven new technological innovations and R&D, increased the competitiveness of the energy industry, and brought technological advancements to other fields.
