Question

The first law of thermodynamics is based on the law of conservation of_________

Answer 1

First law of thermodynamics:

1. The first law of thermodynamics is an application of the board principle known as the law of conservation of energy to the thermodynamic system.
2. It states that the total energy of an isolated system remains constant though it may change from one form to another.
3. In other words, the net energy change of a closed system is equal to the sum of heat transferred to the system and the work done on the system.
4. The mathematical statement of the first law is $∆\mathrm{U}=\mathrm{q}+\mathrm{w}$ , where $∆\mathrm{U}$ is the change in internal energy, $\mathrm{q}$ is the amount of heat supplied to the system, and $\mathrm{w}$ is the work done on the system.

Therefore, the first law of thermodynamics is based on the law of conservation of energy.
