specific heat

n.
1. The ratio of the amount of heat required to raise the temperature of a unit mass of a substance by one unit of temperature to the amount of heat required to raise the temperature of a similar mass of a reference material, usually water, by the same amount.
2. The amount of heat, measured in calories, required to raise the temperature of one gram of a substance by one Celsius degree.

specific heat

1. The ratio of the amount of heat needed to raise the temperature of a certain amount of a substance by one degree to the amount of heat needed to raise the temperature of the same amount of a reference substance, usually water, by one degree. Because molecules of different materials have different weights and sizes, they require different amounts of energy to be heated to a given temperature. Knowing the specific heat of a material makes it possible to calculate how much energy is needed to raise the material's temperature by a given number of degrees.
2. The amount of heat, measured in calories, needed to raise the temperature of one gram of a substance by one degree Celsius.
