WebHeat Capacity Formula The heat capacity, or 'thermal mass' of an object, is defined as the Energy in Joules required to raise the temperature of a given object by 1º C. This is the 'specific heat' of the object (a defined physical/chemical property) multiplied by its mass and the change in temperature. WebThe unit of heat capacity is joule per Kelvin or joule per degree Celsius. Mathematically, Q=CΔT Where Q is the heat energy required to bring about a temperature change of ΔT …
