An ideal gas undergoes an isothermal change in volume with pressure, then
1 $\mathrm{PV}=$ constant
2 $(\mathrm{PV})^{\gamma}=$ constant
3 $\mathrm{PV}^{\gamma}=$ constant
4 $\mathrm{P}^{\gamma} \mathrm{V}=$ constant
Explanation:
A For an ideal gas, the product of pressure and volume ( $\mathrm{P}-\mathrm{V})$ is a constant, if the gas is kept in isothermal condition. In other words, From ideal gas law, PV $=\mathrm{nRT}$. $\mathrm{PV}=\mathrm{nRT}=\text { constant }$ $\therefore \quad \mathrm{PV}=$ constant

In isothermal process, which of the following is not true?
1 Temperature remains constant
2 Internal energy does not change
3 No heat enters or leaves the system
4 none of the above
Explanation:
C We know that, In an isothermal process, Temperature is constant i.e. $\mathrm{PV}=$ constant According to joule's law, internal energy remains constant for isothermal process. In isothermal process, heat can enters or leaves the system, to keep the temperature constant. So, statement (c) is wrong.

One mole of an ideal gas undergoes an isothermal change at temperature $T$, so that its, volume $V$ is doubled, $R$ is the molar gas constant. Work done by the gas during this changes is
1 RT $\log 4$
2 $\mathrm{RT} \log 2$
3 RT $\log 1$
4 $\mathrm{RT} \log 3$
Explanation:
B Given, $\mathrm{V}_{\mathrm{i}}=\mathrm{V}, \mathrm{V}_{\mathrm{f}}=2 \mathrm{~V}$ So, under isothermal process work is given by the relation $\mathrm{W}=\mathrm{RT} \log \left(\frac{\mathrm{V}_{\mathrm{f}}}{\mathrm{V}_{\mathrm{i}}}\right)$ $\mathrm{W}=\mathrm{RT} \log \left(\frac{2 \mathrm{~V}}{\mathrm{~V}}\right)$ $\mathrm{W}=\mathrm{RT} \log (2)$

Which of the following, in general, is a slow process?
1 Isothermal
2 Adiabatic
3 Isobaric
4 Isochoric
Explanation:
A Slow process is generally prefer to isothermal process. The transfer of heat into or out of the system happens so slowly that thermal equilibrium is maintained. i.e. $\Delta \mathrm{T}=0$
