An insulated box containing a diatomic gas of molar mass $m$ is moving with velocity $v$. The box is suddenly stopped. The resulting change in temperature is :-
$\frac{mv^2}{2R}$
$\frac{mv^2}{3R}$
$\frac{mv^2}{5R}$
$\frac{2mv^2}{5R}$
During an adiabatic process, the volume of gas is found to be inversely proportional to the cube of its temperature. The ratio of $\frac{{{C_p}}}{{{C_v}}}$ for the gas is
If a bimetallic strip is heated, it will
Heat is supplied to a di-atomic gas at constant pressure. The ratio of $\Delta Q : \Delta U : \Delta W$ is
In the indicator diagram (in figure), net amount of work done will be
Three moles of an ideal monoatomic gas perform a cycle as shown in the figure. The gas temperature in different states are: $T_1 = 400\, K,\, T_2 = 800\, K,\, T_3 = 2400\, K$ and $T_4 = 1200\,K$ . The work done by the gas during the cycle is .... $kJ$
