Describe the various thermodynamic processes such as isothermal, adiabatic, isobaric, and isochoric.

Sample interview questions: Describe the various thermodynamic processes such as isothermal, adiabatic, isobaric, and isochoric.

Sample answer:

Isothermal Process:

Temperature remains constant throughout the process.
Heat is exchanged between the system and the surroundings, maintaining thermal equilibrium.
Pressure and volume vary inversely (Boyle’s Law).

Adiabatic Process:

No heat is exchanged between the system and the surroundings.
Energy is transferred as work, resulting in changes in pressure and temperature.
Volume and pressure vary according to the specific heat ratio of the gas.

Isobaric Process:

Pressure remains constant throughout the process.
Heat is exchanged, causing changes in volume and temperature.
The work done is equal to the product of pressure and change in volume (W = -PΔV).
