Two newly discovered compounds, Pandemonium and Cascadium, are put into an isolated system with each other. Initially, the Pandemonium is at 90.3 ºC and the Cascadium is at 20.6 ºC, but they are allowed to achieve thermal equilibrium with each other. The Pandemonium sample has a mass that is 4.7x larger than the mass of the Cascadium sample.

Pandemonium has a molar heat capacity that is 2.1x smaller than the molar heat capacity of Cascadium.

John thinks the Pandemonium will undergo a smaller change in temperature than the Cascadium. Is the statement true? If so, why is it correct? If not, explain why it is wrong.
