B$\frac{5}{2}$ $RT$
b $E = \frac{f}{2}RT$; $f = 5$
$\Rightarrow$ $E = \frac{5}{2}RT$

At what temperature will the $rms$ speed of oxygen molecules become just sufficient for escaping from the Earth's atmosphere $?$ (Given: Mass of oxygen molecule $(m)= 2.76 \times 10^{-26}\,kg$ Boltzmann's constant $k_B= 1.38 \times 10^{-23}\,\, JK^{-1}$)
A vessel contains $1$ mole of $O_2$ gas (molar mass $32$) at a temperature $T$. The pressure of the gas is $P$. An identical vessel containing one mole of $He$ gas (molar mass $4$) at a temperature $2T$ has a pressure of
A given sample of an ideal gas occupies a volume $V$ at a pressure $P$ and absolute temperature $T.$ The mass of each molecule of the gas is $m.$ Which of the following gives the density of the gas $?$
A thermally insulated vessel contains an ideal gas of molecular mass $M$ and ratio of specific heats $\gamma$. It is moving with speed $v$ and it's suddenly brought to rest. Assuming no heat is lost to the surroundings, its temperature increases by
