What is the specific heat capacity measured in?

Specific heat capacity is defined as the amount of heat energy required to raise the temperature of 1 kilogram of a substance by 1 degree Celsius (or equivalently, 1 Kelvin). It is quantified in joules per kilogram per degree Celsius (J/kg°C). This unit reflects the energy (in joules) needed for a change in temperature per unit mass of the material and highlights how much energy must be added or removed to change the temperature of that mass of substance by a specific amount.

Understanding this concept is essential for various applications in physics, particularly in thermodynamics, where heat transfer and temperature changes are significant in understanding energy efficiency and material behavior.
