Heat added to a substance goes partly into the translational kinetic energy of its molecules, which directly elevates temperature. For some substances, large proportions of heat also go into vibrations and rotations of the molecules. Would you expect materials in which a lot of energy goes into nontranslational molecular motions to have a high or a low specific heat capacity? Defend your answer.
