WebSep 22, 2024 · Heat capacity is a measure of a system’s total internal energy. This comprises the system’s overall kinetic energy as well as the potential energy of the molecules. It has been demonstrated that a system’s internal energy may be altered by either giving heat energy to it or doing work on it.
Heat 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. The corresponding intensive property is the … See more Basic definition The heat capacity of an object, denoted by $${\displaystyle C}$$, is the limit $${\displaystyle C=\lim _{\Delta T\to 0}{\frac {\Delta Q}{\Delta T}},}$$ where See more The heat capacity can usually be measured by the method implied by its definition: start with the object at a known uniform temperature, add a known amount of heat energy to it, … See more Most physical systems exhibit a positive heat capacity; constant-volume and constant-pressure heat capacities, rigorously defined as partial derivatives, are always positive … See more • Encyclopædia Britannica, 2015, "Heat capacity (Alternate title: thermal capacity)".
