Equal masses of ethanol (C₂H₆O, molar mass 46.07 g mol⁻¹) and glycerol (C₃H₈O₃, molar mass 92.09 g mol⁻¹) are each supplied with the same quantity of thermal energy under identical conditions. The specific heat capacities are 2.46 J g⁻¹ K⁻¹ for ethanol and 2.43 J g⁻¹ K⁻¹ for glycerol.
(a) Without performing numerical calculations, predict which liquid will experience the greater temperature rise and explain your reasoning in terms of both specific and molar heat capacities.
(b) Describe how your prediction would change, if at all, when the experiment is repeated using equal amounts of substance measured in moles rather than in grams. Provide justification.
