In an isobaric process,

Derive the expression for work done by a gas during an isobaric process (constant pressure).

The pressure $P$ of an ideal diatomic gas varies with its absolute temperature $T$ as shown in the figure. The molar heat capacity of the gas during this process is ........... $R$ [$R$ is the gas constant].

$A$ gas expands by $0.25 \ m^{3}$ at a constant pressure of $10^{3} \ N/m^{2}$. Calculate the work done.

Describe the nature of $P-V$ diagrams for isobaric and isochoric processes.

When heat is supplied to a monoatomic gas,it expands at constant pressure. What fraction of the heat supplied is converted into work?
