Chemistry - Thermodynamics - I Question with Solution | TestHub
Find the number of correct statements:
1) is a state function.
2) is independent of for a perfect (ideal) gas.
3) for every thermodynamic system at rest in the absence of an external field.
4) A process in which the final temperature equals the initial temperature must be an isothermal process.
5) remains constant in every isothermal process in a closed system.
6) for every cyclic process.
7) for every cyclic process.
8) A thermodynamic process is specified by specifying only the initial and final state of the system.
9) P-V work is usually negligible for solids and liquids.
10) If neither heat nor matter can enter or leave a system, that system must be isolated.
