How is specific heat capacity measured?

Specific heat capacity is measured in joules per kilogram per degree Celsius, which is represented as Jkg^-1C^-1. This unit reflects the amount of energy in joules required to raise the temperature of one kilogram of a substance by one degree Celsius.

When determining specific heat capacity, it is essential to understand that the temperature change can be measured in Celsius (or Kelvin, as they are equivalent in magnitude when dealing with temperature differences), and the mass of the material involved is measured in kilograms. Therefore, the combination of these components leads to the specific unit of measurement for specific heat capacity.

The other options presented do not accurately represent the relationship of energy, mass, and temperature change relevant to specific heat capacity. For example, Jkg^-1K^-1 is commonly used for temperature change in Kelvin, which is acceptable, but the most conventional context in thermodynamics often uses degrees Celsius. The other units listed, such as Jm^-1C^-1 and Jkg^-1F^-1, do not correspond to any standard physical quantity associated with specific heat capacity.
