What Is Specific Heat Capacity? Definition and Explanation Specific heat capacity, often simply called specific heat, is defined as the amount of heat energy required to raise the temperature of a unit mass of a substance by one degree Celsius (or Kelvin). It is a material-specific property, meaning different substances have different capacities to store heat. Mathematically, it is expressed as: - Q = mcΔT Where: - Q = heat energy added or removed (in joules) - m = mass of the substance (in kilograms) - c = specific heat capacity (J/kg°C) - ΔT = change in temperature (in °C or K) Units of Specific Heat The SI unit for specific heat capacity is Joules per kilogram per degree Celsius (J/kg°C). Sometimes, you might encounter calories per gram per degree Celsius (cal/g°C) in older or non-SI contexts, but SI units are standard in scientific calculations.
