Q.Define the following terms: a. isothermal process b. adiabatic process c. isobaric process d. isochoric process

Step 1. Isothermal process: the system's temperature remains constant throughout the change from its initial to final state ($dT=0$); the system exchanges heat with its surroundings to maintain this, typically carried out in a thermostat.

Step 2. Adiabatic process: no heat ($q$) is exchanged between the system and its surroundings during the process ($q=0$); the system is thermally insulated, so if it does work its temperature falls, and if work is done on it, its temperature rises.

Step 3. Isobaric process: the system's pressure remains constant during its change from initial to final state ($dP=0$). …
