If we know that for a certain gas 2/5 of the total kinetic energy of the molecules is rotational and 3/5 is due to the motion of their centres of mass. a. calculate the average kinetic energy due to the motion of the centre of mass of one of these molecules at 300 k. b. if the temperature is to be increased by 20â°c, how much energy must be supplied to a mole of the gas to produce this temperature rise at constant pressure?
