Specific Heat Capacity Concepts
Definition of Specific Heat Capacity
Specific heat capacity (c) is a material property that measures the amount of heat required to raise the temperature of a unit mass of the material by one degree Celsius or one Kelvin. Its SI unit is joules per kilogram per Kelvin (J/kg·K).
Examples of Specific Heat Capacities
- Water: 4187 J/kg·K
- Aluminum: 900 J/kg·K
- Iron: 450 J/kg·K
- Wood: 1700 J/kg·K
- Air: 1005 J/kg·K
Relation to Heat Transfer
Specific heat capacity is directly related to the amount of heat required to raise the temperature of a substance. A substance with a high specific heat capacity requires more heat to raise its temperature by the same amount compared to a substance with a low specific heat capacity.
