Nesterboy [21]

Answer;

The temperature change for the second pan will be lower compared to the temperature change of the first pan

This means; the quantity of heat depends on the mass, specific heat capacity of a substance and also the change in temperature.

-Maintaining the same quantity of heat, with another pan of the same mass and greater specific heat capacity would mean that the change in temperature would be much less lower.
