Question

Substance A and substance B have the same weight at the same temperature. When the same amount of heat was applied to each substance, the temperature of substance A increased by 10 degree C and that of substance B by 5 degree C. Which one best describes the temperature difference between the two substances? The enthalpy of formation of substance A must be greater than that of substance B. The enthalpy of formation of substance A must be smaller than that of substance B. The specific heat of substance A must be greater than that of substance B. The specific heat of substance A must be smaller than that of substance B. No answer (i.e., none of them gives a proper explanation.)

Explanation / Answer

heat, q = mcdT

dT = q = /mc

q and m are same

Change in temperature in inversely proportional the the specific heat of substance and hence

specific heat of substance must be smaller than that of substance B
