The kinetic energy of $1$ gram-mole of Argon at $127^{\circ}C$ is .... $J$.

The internal energy of a monoatomic ideal gas molecule is

The kinetic energy of translation of $20 \, g$ of oxygen at $47^{\circ}C$ is (molecular weight of oxygen is $32 \, g/mol$ and $R = 8.3 \, J/mol \cdot K$).

Write the equation relating pressure,volume,and internal energy of an ideal gas.

If the $r.m.s.$ velocity of a gas is $v_{rms} = 1840 \ m/s$ and its density is $\rho = 8.99 \times 10^{-2} \ kg/m^3$,what is the pressure of the gas?

An ideal gas in a container of volume $500 \text{ c.c.}$ is at a pressure of $2 \times 10^5 \text{ N/m}^2$. The average kinetic energy of each molecule is $6 \times 10^{-21} \text{ J}$. The number of gas molecules in the container is:
