On what does the heat required to increase the temperature of a substance depend?

Define molar specific heat and state its $SI$ unit.

The specific heat of a substance at temperature $T^{\circ}C$ is given by $C = \alpha T^2 + \beta T + \gamma$. The amount of heat required to raise the temperature of a mass $m \, g$ of the substance from $0^{\circ}C$ to $T_o^{\circ}C$ is .......

What is the value of the specific heat of all substances at absolute zero temperature?

By what property can the temperature difference be determined if the state of a substance does not change during the absorption of a given amount of heat?

On which does the heat in a substance depend?
