What is Specific Heat Capacity?
Specific heat capacity is the amount of heat energy required to raise the temperature of a substance per unit of mass. In simple terms, it tells you how much energy you need to heat up 1 kg of a material by 1°C.
Q = m × c × ΔT
- Q (Heat Energy): Measured in Joules (J).
- m (Mass): Measured in kilograms (kg).
- c (Specific Heat Capacity): Measured in J/kg°C. Water has a very high specific heat of about 4,184 J/kg°C.
- ΔT (Temperature Change): The difference between the final and initial temperatures in °C or Kelvin.
