On which does the heat in a substance depend?

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?

How much energy is produced in the burning of $1\, kg$ of coal?

During illness,an $80 \, kg$ man had a fever of $102.2^\circ F$ instead of his normal body temperature of $98.6^\circ F$. Assuming that the human body is mostly water,how much heat is required to raise his temperature by that amount in $kcal$?

Explain the heat capacity of a substance and write its equation and unit.

What is the heat capacity of copper of $40 \, g$ and specific heat $0.3 \, erg \, g^{-1} (^{\circ} C)^{-1}$?
