Question

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

• 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.

Answer 1

Answer: (D)

Temperature, internal energy and volume depend upon states
