Heat capacity - Wikipedia
WebHeat capacity or thermal 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. The SI unit of heat capacity is joule per kelvin (J/K). Heat capacity is an extensive property.

WebApr 4, 2024 · Heat capacity, ratio of heat absorbed by a material to the temperature change. It is usually expressed as calories per degree in terms of the actual amount of material being considered, most commonly a mole (the molecular weight in grams). The heat capacity in calories per gram is called specific heat.

WebMay 13, 2023 · The heat capacity ( C) of a body of matter is the quantity of heat ( q) it absorbs or releases when it experiences a temperature change ( ΔT) of 1 degree Celsius (or equivalently, 1 kelvin) C = q ΔT. Heat capacity is determined by both the type and amount of substance that absorbs or releases heat.
