How is thermal capacity defined?

Thermal capacity refers to an object's ability to store thermal energy. When we say it measures how well an object can hold thermal energy, we are identifying the capacity of the material to absorb heat without experiencing a significant change in temperature. This property is crucial in various applications since materials with a high thermal capacity can help maintain stable temperatures, which is essential in systems where temperature regulation is critical, like in climate control or thermal insulation.

In contexts where materials are designed to retain heat—like in thermal mass constructions, cookware, or even in aerospace components—understanding thermal capacity becomes fundamental. It helps in predicting how materials will behave when they are subjected to heat and plays a key role in thermal management strategies.
