(a) Define the coefficient of cubical (volume) expansion for a substance.
(b) An ideal gas is kept at constant pressure. Show that its coefficient of cubical expansion is equal to the reciprocal of its absolute temperature T0.
(c) Without doing any numerical calculation, explain whether the coefficient of cubical expansion of an ideal gas at 300K is larger or smaller than that of common metals whose linear expansion coefficient is of the order 10−5K−1. Give a brief reason for your answer.
