Embibe Experts Solutions for Exercise 4: Assignment

1 mole of $H_2$ at pressure $P_0$ and temperature $T_0$ and $1$ mole of $He$ at pressure $2P_0$ and temperature $T_0$ respectively are kept in two different containers. The ratio of their $\mathrm{rms}$ speeds, $C_{H_2}:C_{He}$ is

Two containers of equal volume contain identical gases at pressures $P_1$ and $P_2$ and absolute temperatures $T_1$ and $T_2$ respectively. The vessels are joined and the gas reaches a common pressure $P$ and a common temperature $T.$ Then

A gas mixture consists of molecules of type $1,2$ and $3$ with molecular masses $m_1>m_2>m_3$. Which gas has maximum average translational kinetic energy per molecule?

If the indicator diagram for expansion of gas is as shown, the gas

Choose the wrong statement.

If $E$ is the total energy, $U$ is the potential energy and $K$ is the kinetic energy of a mole of an ideal gas, then

A real gas deviates from perfect gas behaviour as its molecule

If the atoms in a diatomic molecule can vibrate, the molecule has
