If the r.m.s. speed of a monoatomic gas is increased up to 2 times and the process is done adiabatically, then the ratio of initial volume to final volume will be

Options:

Answer:

Solution:

$v_{r m s} \propto T$ : doubling $v_{r m s}$ makes $T$ four times.

$Adiabatic, monoatomic (γ = 5/3) : T V^{γ - 1} = T V^{2/3} = const. \frac{V _{i}}{V _{f}} = (\frac{T _{f}}{T _{i}})^{3/2} = 4^{3/2} = 8.$
