At $0 \; K$,which of the following properties of a gas will be zero?

The temperature of a gas is $-68^\circ C$. At what temperature in $^\circ C$ will the average kinetic energy of its molecules be twice that of at $-68^\circ C$?

The kinetic energy of one mole of gas at $300 \ K$ temperature is $E.$ At $400 \ K$ temperature,the kinetic energy is $E'.$ The value of $E'/E$ is

The kinetic energy of one mole of a gas at $300 \, K$ is $E$. If the kinetic energy at $400 \, K$ is $E'$,then what is the ratio $E'/E$?

$A$ flask contains Hydrogen and Argon in the ratio $2:1$ by mass. The temperature of the mixture is $30^{\circ} C$. The ratio of average kinetic energy per molecule of the two gases $(K_{\text{argon}} / K_{\text{hydrogen}})$ is: (Given: Atomic weight of $Ar = 39.9$)

Pressure of an ideal gas is increased by keeping temperature constant. What is the effect on the kinetic energy of molecules?
