As ideal monatomic gas of $\mathbf{1 . 5}$ moles is heated at a constant pressure $2 \mathrm{~atm}$ so that its temperature from $30^{\circ} \mathrm{C}$ to $130^{\circ} \mathrm{C}$. Work done by the gas is-
(Universal gas constant $=8.3 \mathrm{~J} \mathrm{~mol}^{-1} \mathrm{~K}^{-1}$ )

A sample of an ideal gas is taken through the cyclic process $\mathrm{ABCA}$ as shown in figure. It absorbs, $40 \mathrm{~J}$ of heat during the part $\mathrm{AB}$, no heat during $B C$ and rejects $60 \mathrm{~J}$ of heat during CA. A work of $50 \mathrm{~J}$ is done on the gas during the part BC. The internal energy of the gas at $A$ is $1560 \mathrm{~J}$. The work done by the gas during the part $C A$ is:

A thermally insulated vessel contains an ideal gas of molecular mass $M$ and ratio of specific heats 1.4. Vessel is moving with speed $v$ and is suddenly brought to rest. Assuming no heat is lost to the surrounding and vessel temperature of the gas increases by:
$\text { ( } \mathrm{R}=\text { universal gas constant) }$
