$\Delta W = 0$,for the process

$A$ monoatomic gas is supplied heat $Q$ very slowly while keeping the pressure constant. The work done by the gas will be

Which of the following graphs between pressure $(P)$ and volume $(V)$ correctly shows an isochoric process?

The ratio of work done by an ideal rigid diatomic gas to the heat supplied to the gas in an isobaric process is (in $/7$)

$A$ diatomic gas $(\gamma = 1.4)$ does $200 \,J$ of work when it is expanded isobarically. The heat given to the gas in the process is: (in $\,J$)

$A$ 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 $\text{ kJ}$)
