Solution

Specific heat capacity of a substance is defined as the heat required to rise the temperature of 1 g of the substance by 1 ^oC.
Thermal capacity is the capacity of a substance to store heat. The change in thermal heat capacity of a body of 1 g when the temperature is raised by 1 ^oC is the specific heat capacity.
Substance with high specific heat will take more time to increase temperature. So, when two different substances of same mass are heated equally then the substance with low specific heat will have more temperature rise.
