Question

What do you mean by degradation of energy? Explain it by taking two examples of your daily life.

Answer 1

: We have to remember that the capacity to do a word or supply heat is known as energy. Energy is a conserved quantity and it is a quantitative property. The energy should be required to a physical system or a body to do the work or heat the system. According to the law of conservation of energy, it expresses that the energy can neither be created nor be destroyed. Which means, we can’t create the energy. In an isolated system, the total energy of it always remains constant.

Complete answer:
As we know that during a chemical reaction, the chemical energy will be released in the form of heat. The energy is mainly stored in the bonds present in the chemical reaction. If the heat is released during a chemical reaction, that reaction is known as an exothermic reaction. If the heat gains from the surrounding, that reaction is endothermic.
The moderation decrease or reduction of useful energy due to friction or other processes is known as degradation energy. When a given quantity of energy is converted from one form to another form which can form less amount of work. The degradation of energy takes place in many field, and the examples is;
The more amount of electrical energy is misused in the form of heated energy when the electrical devices conduct the electricity.
And a huge amount of heat energy formed from the fuel is declared when cooking the food over the fire. There is no use of energy liberation, rather it causes pollution.

Note:
In the case of degradation of energy, it takes place when a given amount of energy is converted to its different forms which produces very less amount of work. The most common degraded form of energy is heat. Energy exists in many forms, which is heat energy, light energy, gravitational energy and mechanical energy, sound energy, chemical energy, atomic energy, electrical energy, etc.
