Question

Isobaric and Adiabatic Processes

Hint:

In an isobaric process, pressure remains constant, whereas in an adiabatic process, no heat is exchanged with the surroundings.

Answer 1

Isobaric Process: An isobaric process takes place at a constant pressure, meaning: \[ \Delta P = 0 \] Example: - Heating water in an open container at constant atmospheric pressure. The work done during an isobaric process is given by: \[ W = P \Delta V \] Adiabatic Process: An adiabatic process occurs when there is no heat exchange between the system and its surroundings. \[ q = 0 \] Example: - Sudden expansion or compression of a gas in an insulated container. For an adiabatic process, the relationship between pressure and volume is: \[ PV^\gamma = \text{constant} \]
