Q. Some of the thermodynamic parameters are state variables while some are process variables. Some grouping of the parameters are given. Choose the correct one.

Kinetic Theory Report Error

A

State variables : Temperature, No of moles Process variables : Internal energy, work done by the gas.

B

State variables : Volume, Temperature Process variables : Internal energy, work done by the gas.

C

State variables : Work done by the gas, heat rejected by the gas Process variables : Temperature, volume.

D

State variables : Internal energy, volume Process variables : Work done by the gas, heat absorbed by the gas.

Solution:

Temperature, internal energy and volume depend upon states
