The absolute zero is the temperature at which

Estimate the average thermal energy of a helium atom at:
$(i)$ room temperature $(27^{\circ} C)$,
$(ii)$ the temperature on the surface of the Sun $(6000\; K)$,
$(iii)$ the temperature of $10$ million kelvin (the typical core temperature in the case of a star).

If $E$ is the kinetic energy per mole of an ideal gas and $T$ is the absolute temperature,then the universal gas constant is given as

The relationship between pressure $P$,volume $V$,and total internal energy $E$ for an ideal gas is:

In the kinetic theory of gases,a molecule of mass $m$ of an ideal gas collides with a wall of a vessel with velocity $V$. The change in the linear momentum of the molecule is

According to the kinetic theory of gases,
