Question

Identify and name the thermodynamic processes marked as $1, 2, 3$ and $4$ as shown in figure.

✓

Answer

Isochoric process as it occurs at constant volume.
Adiabatic process because its slope is steeper than the process indicated by $3,$ which is isothermal process.
Isothermal process.
Isobaric process as it occurs at constant pressure.

The height of mercury column in a barometer in a Calcutta laboratory was recorded to be 75 cm . Calculate this pressure in SI and CGS units using the following data: Specific gravity of mercury = 13.6, Density of water = $10^3 \mathrm{~kg} / \mathrm{m}^3, \mathrm{~g}=9.8 \mathrm{~m} / \mathrm{s}^2$ at Calcutta. Pressure $=\mathrm{h} \rho \mathrm{g}$ in usual symbols.
