Heat capacities

Heat capacity or thermal capacity is a measurable physical quantity equal to the ratio of the heat added to (or removed from) an object to the resulting temperature change. The unit of heat capacity is joule per kelvin ${\displaystyle \mathrm {\tfrac {J}{K}} }$, or kilogram metre squared per kelvin second squared ${\displaystyle \mathrm {\tfrac {kgm^{2}}{Ks^{2}}} }$ in the International System of Units (SI). The dimensional form is L²MT⁻²Θ⁻¹. Specific heat is the amount of heat needed to raise the temperature of one kilogram of mass by 1 kelvin.
