Why is energy balanced? What is the significance of maintaining energy balance

Energy is neither created out of thin air nor disappears for no reason, but is transferred from one object to another, or transformed.

Because matter doesn't disappear out of thin air.

Energy is not created or disappeared, it is only transferred from one object to another.

The upstairs point is wrong, Einstein's mass-energy equation does not say that mass is converted into energy, but that one mass is equal to one part energy, which means that you have as much mass as you have energy.

As for the atomic bomb you are talking about, it is a problem of atomic loss, but the loss is actually just an illusion, and the mass of the loss is radiated out in various forms, which is what you call radiant energy.

A photon has mass, and as long as there is energy, its mass can be calculated using the mass-energy equation, so as long as the energy of the photon is given, its mass can be calculated by using e=mc.

In classical physics, energy is conserved, but each stage of science is not one-size-fits-all, and there are certain limitations.

In high-energy physics, energy is not conserved at all, energy can be converted into mass, and mass in turn can be converted into energy! According to Einstein's mass-energy equation e=mc2, we can only say "conservation of mass and energy", that is, the synthesis of "the indestructibility of matter" and "the theorem of conservation of energy"!

For example, in the case of an atomic bomb**, although fusion or fission is transformed into other elements, the mass of the reactants is greater than the mass of the product because of the release of radiant energy!! Otherwise, the volume of the sun will not be more and more consumed, right?

Energy can also be converted into matter, do photons have mass? According to Albert Einstein, no! But for some fusion reactions that require light, the mass of the reactants is smaller than the product, can you say that the photons do not become matter? You can't always say that nuclear energy is also "internal energy"?

Your argument is obviously practical for simple physical processes with no internal energy level transitions. Of course, "conservation" may be a law of nature, but at each stage, the object of "conservation" changes with human understanding.

This is something that has been thought about for a long time and spent a lot of energy before it came to it, and it cannot be explained in half a word.

According to Einstein's mass-energy equation e=mc2, mass is conserved, matter does not disappear or arise out of thin air, and energy is naturally conserved.

yes, who will create energy.

He has blessed mankind.

In various physiological states, the vast majority of energy intake comes from the chemical energy contained in food, while expenditure includes energy contained in feces, urine and digestive tract gases, and special thermogenesisThe energy expended to maintain basic life activities, production, and external work. The sum of the energy of the first trophic level is the energy absorbed by the second trophic level plus the energy of the excrement and the energy decomposed by the decomposer.

Energy balance does not require everyone to balance their daily energy intake, but requires adults to consume the same amount of energy as they consume in 5-7 days.

Conservation of energy. According to the law of conservation of energy, the ratio of the income energy to the expenditure energy of a system in a given time. The system referred to here refers to the objective entity of a certain organizational scope and physical objects for energy balance.

In terms of scope and physical objects, the energy balance includes the energy provided by primary energy and secondary energy, as well as various forms of energy carried by working fluids and materials, including heat, light, electricity, force and other energy. The most widely used is the energy balance in the form of thermal energy, which is called thermal equilibrium. In physics, there is also the concept of conservation of energy.

Nutrition is the science of the nature, distribution, metabolic role of nutrients in food, and the consequences of insufficient food intake. Nutrients are chemicals in food that can be absorbed and used to promote health. Certain nutrients are necessary because they cannot be synthesized by the body and therefore must be obtained from food.

Essential nutrients include vitamins, inorganic salts, amino acids, fatty acids, and certain carbohydrates that act as energy**. Non-essential nutrients are nutrients that the body can synthesize from other chemicals, although they can also be obtained from the diet. Nutrients are generally divided into macronutrients and micronutrients.

The English word nutrition is interpreted as: an organic process by which an organism absorbs, uses food and liquids to maintain normal function, growth, and self-maintenance. A study of the relationship between food and beverages on health and disease.

A concept and idea that pursues the best combination of nutrients and all foods to achieve the best performance of the body. Nutrients refer to the chemical components of food that can provide the body with energy, body building blocks, tissue repair, and physiological regulatory functions. Nutrients are used to maintain human health and to provide the necessary for growth, development, and labor.

Essential nutrients for the human body include proteins, fats, sugars, inorganic salts (minerals), vitamins, water, and fiber.
