$A$ gas expands under constant pressure $P$ from volume $V_1$ to $V_2$. The work done by the gas is

$0.08 \text{ kg}$ of air is heated at constant volume through $5^{\circ} \text{C}$. The specific heat of air at constant volume is $0.17 \text{ kcal/kg}^{\circ} \text{C}$ and $J = 4.18 \text{ J/cal}$. The change in its internal energy is approximately: (in $\text{ J}$)

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

$A$ diatomic gas $(\gamma=1.4)$ does $100 \,J$ of work in an isobaric expansion. The heat given to the gas is: (in $\,J$)

Which one of the following statements is wrong for an isobaric process?

The thermodynamic process in which the work done on or by the gas is zero is:
