For an ideal gas, interval energy can only be translational K.E. Why ?

At ordinary temperatures, the molecules of an ideal gas have only translational and rotational kinetic energies. At high temperatures they may also have vibrational energy. As a result of this, at higher temperature

Can a ideal gas be expanded at constant internal energy.

There is no change in internal energy for an ideal gas at constant temperature. Internal energy of an ideal gas is a function of temperature only.

There is no change in internal energy for an ideal gas at constant temperature. Internal energy of an ideal gas is a function of temperature only.

Prove that the pressure of an ideal gas is numerically equal to two third of the mean translational kinetic energy per unit volume of the gas.
