Heat Capacity

1. Heat capacity is the amount of heat energy required to raise the temperature of a body a specified amount.
2. Heat capacity is a physical property of matter, defined as the amount of heat to be supplied to an object to produce a unit change in its temperature.

In SI units, heat capacity (symbol: C) is the amount of heat in joules required to raise the temperature 1 Kelvin. Heat capacity of a material is affected by the presence of hydrogen bonds. The intermolecular forces make it more difficult to increase the kinetic energy and thus temperature of a material. This is why water, ammonia, and ethanol have high heat capacity values. Impurities in a sample also have a dramatic effect on heat capacity. Heat properties of an alloy can vary dramatically from that of its component elements. Trace amounts of contaminants in a sample can change its heat capacity versus that of a pure sample.
