The ratio of work done by an ideal monoatomic gas to the heat supplied to it in an isobaric process is

$A$ cyclic process is shown in the figure. The work done during the isobaric expansion is ...... $J$.

$A$ frictionless piston-cylinder based enclosure contains some amount of gas at a pressure of $400 \text{ kPa}$. Heat is transferred to the gas at constant pressure in a quasi-static process. The piston moves up slowly through a height of $10 \text{ cm}$. If the piston has a cross-sectional area of $0.3 \text{ m}^2$, the work done by the gas in this process is: (in $\text{ kJ}$)

In which thermodynamic process,volume remains same?

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

$A$ diatomic gas,having $C_{p} = \frac{7}{2} R$ and $C_{v} = \frac{5}{2} R$,is heated at constant pressure. The ratio $dU : dQ : dW$ is:
