Every substance takes a different amount of heat to increase its temperature . It usually takes less heat to raise the temperature of a metal than for other materials, like water or air. The specific heat for a material is the amount of heat required to raise the temperature of a specific mass by one degree. The terms heat and temperature are sometimes used synonymously, but they do not mean the same thing. When two objects with different temperatures are in contact, there is an exchange of energy from the hotter object to the colder object.
Heat is the amount of energy that transfers from the hotter object to the colder object.
