Specific Heat Capacity of some common materials
Specific heat capacity, often simply called specific heat, is a measure of the amount of heat energy required to raise the temperature of a substance by a certain amount. It is typically expressed in units of joules per gram per degree Celsius (J/g·°C). The specific heat capacity of a substance depends on its molecular structure and composition, as well as the temperature and pressure at which it is measured. Different substances have different specific heat capacities, which means that some substances are better at absorbing and retaining heat than others. This property is important in many applications, including cooking, heating and cooling, and energy storage.
The following table shows the specific Heat Capacity of some common materials.
