Two separate 1.00-mol samples are each supplied with the same quantity of thermal energy. Substance X has a specific heat capacity of 0.900 J g⁻¹ K⁻¹ and a molar mass of 40.0 g mol⁻¹, whereas substance Y has a specific heat capacity of 4.18 J g⁻¹ K⁻¹ and a molar mass of 18.0 g mol⁻¹. Which of the following best describes the temperature changes of the two samples?
a) Both substances experience the same temperature increase.
b) The temperature of substance Y increases more than that of substance X because its specific heat capacity is larger.
c) The temperature of substance X increases more than that of substance Y.
d) The temperature changes cannot be compared because the masses of the two samples are different.
