Question

Explain the applications of Thermodynamics.​

Answer 1

Answer:

Thermodynamics is a branch of science which deals with the study of heat and temperature and their relation to other forms of energy. It applies to a variety of science and engineering topics such as chemical, physical, and mechanical engineering. This branch was basically developed out of a desire to improve the efficiency of steam engines.

Explanation:

1.    Thermodynamics deals only with the properties of macroscopic systems.
2.    It does not tell anything about mechanism of process.
3.    It does not consider the time factor.
4.    It does not consider the internal sructure of atoms and molecules.

Here are some more applications of thermodynamics:

   Sweating in a crowded room: In a crowded room, everybody (every person) starts sweating. The body starts cooling down by transferring the body heat to the sweat. Sweat evaporates adding heat to the room. Again, this happens due to the first and second law of thermodynamics in action. One thing to keep in mind, heat is not lost but transferred attaining equilibrium with maximum entropy.

   Melting of ice cube: Ice cubes in a drink absorb heat from the drink making the drink cooler. If we forget to drink it, after some time, it again attains room temperature by absorbing the atmospheric heat. All this happens as per the first and second law of thermodynamics.

We use thermodynamic principles to experience success and happiness. Don’t believe? Let’s see how. You and your family is a complex adaptive system having a finite amount of energy at any given time. To thrive and survive, you have to get food externally. You need mental and emotional stimulation from the environment. Here entropy plays a major part. Entropy is a measure of things falling apart in life or business/work (as per the second law) greater the entropy, faster will be the rate of deterioration of life and business. Everybody must first use his/her available energy to keep its internal entropy in check. Only then he/she can engage with the external world in pursuit of success and happiness.

Question: How is thermodynamics applied to the biological system?

Answer: The best example is the generation of ATP. Energy stored in the bonds of ATP drives the synthesis of glucose-6-phosphate. The compounds such as acyl phosphate, enol phosphate, etc. also have a high phosphate group transfer potential.
