Question

Thermodynamics is concerned with: (a) total energy of a system (b) energy changes in a system (c) rate of a chemical reaction (d) mass changes in nuclear reactions

Answer 1

Explanation:

 Energy is the ability to bring about change or to do work. Thermodynamics is the study of energy.

option B. is correct answer

Initially thermodynamics was carried for heat (Thermos) changes but now it involves all kinds of energy changes.

Hope its helpful for you dear ❤❤

Answer 2

Answer:

(b) energy changes in a system

Explanation:

Thermodynamics is the study of the relations between heat, work, temperature, and energy. The laws of thermodynamics describe how the energy in a system changes and whether the system can perform useful work on its surroundings.

There are three laws of thermodynamics which are as follows.

1. 1st Law of Thermodynamics - Energy cannot be created or destroyed.
2. 2nd Law of Thermodynamics - For a spontaneous process, the entropy of the universe increases.
3. 3rd Law of Thermodynamics - A perfect crystal at zero Kelvin has zero entropy.
