An ideal gas is a gas where the atoms do not exert forces on each other but they do collide with the walls of the container (in elastic collisions).


The number of molecules per unit volume in the sample is 20. The mass of each molecule is 10<sup>-20</sup>kg. The mean of speed squared is 4m<sup>2</sup>/s<sup>2</sup>. What is the value of internal energy of the gas? Assume volume of container is 0.02m<sup>3</sup>.
