371236 Assertion :
We can not change the temperature of a body without giving (or taking) heat to (or from) it.
Reason :
According to principle of conservation of energy, total energy of a system should remain conserved.

371237 The internal energy of a perfect monoatomic gas is

371238 \(1\;c{m^3}\) of water at its boiling point absorbs \(540\,cal\) of heat to become steam with a volume of \(1671\;c{m^3}\) and pressure of \(1.013 \times {10^5}N{m^{ - 2}}\) and the mechanical equivalent of heat \( = 4.19J\,ca{l^{ - 1}}\). The energy spent in this process in overcoming intermolecular forces is

371239 \(2\;g\) of \({H_2}O\) changes from liquid to vapour phase at constant pressure at \(2\;atm\). The volume increases from \(1 \mathrm{cc}\) to \(3342\,cc\). The heat of vaporisation at this pressure is \(540\,cal/g\). The increase in internal energy of water is

371240 A total of \({48 J}\) heat is given to one mole of helium kept in a cylinder. The temperature of helium increases by \({2^{\circ} {C}}\). The work done by the gas is (Given, \({R=8.3 {JK}^{-1} {~mol}^{-1}}\).)
