In a thermodynamic isobaric process:

Which one of the following $p-V$ diagrams is correct for an isochoric process?

$0.08 \text{ kg}$ 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 an ideal gas $\left(\gamma = \frac{5}{3}\right)$ is heated under constant pressure,then what percentage of given heat energy will be utilised in doing external work (in $\%$)?

The percentage of heat supplied to a diatomic ideal gas that is converted into work in an isobaric process is

Two kg of water is converted into steam by boiling at atmospheric pressure. The volume changes from $2 \times 10^{-3} \ m^3$ to $3.34 \ m^3$. The work done by the system is about ....... $kJ$.
