During a reversible adiabatic process, the pressure of a gas is found to be proportional to the cube of its absolute temperature. The ratio $\frac{C_p}{C_V}$ for the gas is:

$A$ monoatomic ideal gas,initially at temperature $T_1$,is enclosed in a cylinder fitted with a frictionless piston. The gas is allowed to expand adiabatically to a temperature $T_2$ by releasing the piston suddenly. $L_1$ and $L_2$ are the lengths of the gas columns before and after the expansion,respectively. The ratio $\frac{T_2}{T_1}$ is:

$A$ certain mass of gas occupies a volume of $300 \, cc$ at $27 \, ^oC$ and $620 \, mm$ pressure. The volume of this gas at $47 \, ^oC$ and $640 \, mm$ pressure will be ........... $cc$.
