Two substances A and B, initially at different temperatures, are thermally isolated from their surroundings and allowed to come into thermal contact. The mass of substance A is twice the mass of substance B, but the specific heat capacity of substance B is four times the specific heat capacity of substance A. Which substance will undergo a larger change in temperature?

Answer #1

Substance A will undergo a larger change in temperature.

As we know,

change in temperature= Q/mc where, Q=heat supplied, m= mass of the substance and c= specific heat.

So, eventually as specific heat of B is four times the specific heat capacity of substance A and mass of A is twice B there will be larger change in temperature in substance A.
