    A cylinder made of perfectly non conducting material closed at both ends is divided into two equal parts by a heat proof piston. Both parts of the cylinder contain the same masses of a gas at a temperature $t_0 = 27^o$ and pressure $P_0 = 1$ atm. Now if the gas in one of the parts is slowly heated to $t = 57^oC$ while the temperature of first part is maintained at $t_0$ the distance moved by the piston from the middle of the cylinder will be.... $cm$ (length of the cylinder $= 84\,\, cm$)

    $Assertion :$ The ratio of $\frac{C_p}{C_v}$ for an ideal diatomic gas is less than that for an ideal monoatomic gas (where $C_p$ and $C_v$ have usual meaning).
    $Reason :$ The atoms of a monoatomic gas have less degrees of freedom as compared to molecules of the diatomic gas.
