Answer 1

Answer:

According to kinetic theory of gases at absolute zero temperature is attained when

Answer 2

The kinetic energy of the molecules is zero.

According to the kinetic theory of gases, the average kinetic energy eg. translation per molecule of a gas is directly proportional to the absolute temperature of the gas.

The pressure exerted by an ideal gas is given by

$P=\frac{1}{3} (\frac{m}{v} )C^2=\frac{1}{2}PC^2$

where C is the root mean square speed of molecules of the gas.

$PV=\frac{1}{3}MC^2\\ RT=\frac{1}{3}MC^2 [\therefore PV=RT]$

$C^2=\frac{3RT}{m}\Rightarrow C2\sqrt{T}$

The square root of the absolute temperature of an ideal gas is directly proportional to root mean square velocity of its molecule.

Now at $C=0,T=0$

Absolute zero of temperature is defined as that temperature at which the root mean square velocity of the gas molecules is reduced to zero.

It means molecules motion cases at absolute zero i.e kinetic energy of the molecules becomes zero at absolute zero temperature.
