Specific Heat

the quantity of heat required to change the temperature of a unit of mass of any substance 1 deg. C. It takes more heat to warm alcohol than it does to warm a pound of lead to the same temperature. We say therefore that the specific heat of alcohol is greater than that of lead. The amount of heat required to raise the temperature of a unit of water 1 deg. C. is taken as the unit of specific heat. If we say that the specific heat of glass, for instance, is two-tenths, we mean that the same amount of heat will raise the temperature of a pound of glass five times as much as it will a pound of water. For a number of common subjects the following is
