Question

Q.5 What is an Isobaric process ? Give one example of it. Obtain the expression

C p – C v = R. Draw the p-V diagram of isobaric process. ( each mark 4)
​

Answer 1

Answer:

The heat transferred to the system does work but also changes the internal energy of the system. In an isobaric process for a monatomic gas, heat and the temperature change satisfy the following equation: Q=52NkΔT Q = 5 2 N k Δ T . For a monatomic ideal gas, specific heat at constant pressure is 52R 5 2 R .

Answer 2

Answer:

An isobaric process is one where the pressure of the system (often a gas) stays constant. 'Iso' means the same, and 'baric' means pressure.

An example of the isobaric process includes the boiling of water to steam or the freezing of water to ice. In the process, a gas either expands or contracts to maintain constant pressure and hence the net amount of work is done by the system or on the system.
