If a gas expands at constant temperature,it indicates that

The diffusion coefficient of an ideal gas is proportional to its mean free path and mean speed. The absolute temperature of an ideal gas is increased $4$ times and its pressure is increased $2$ times. As a result,the diffusion coefficient of this gas increases $x$ times. The value of $x$ is

State the relationship between kinetic energy and temperature for an ideal gas.

$A$ bottle of dry ammonia and a bottle of dry hydrogen chloride connected through a long tube are opened simultaneously at both ends. The white ammonium chloride ring first formed will be:

According to the kinetic theory of gases,the energy per mole of a gas is equal to:

What is the total kinetic energy of $0.6 \ mol$ of an ideal gas at a temperature of $27 \ ^oC$ in $J$?
