Study Notes
- Heat capacity is the amount of heat absorbed per unit temperature change.
- Specific heat capacity is the amount of heat absorbed per unit mass and temperature change.
- Molar heat capacity is the amount of heat absorbed per unit mole and temperature change.
- Heat capacity is an extensive property, dependent on the amount of material.
- Specific heat capacity is an intensive property, independent of the amount of material.
- Molar heat capacity is an intensive property, dependent only on the identity of the substance.
- Water has a high specific heat capacity, while metals have a low specific heat capacity.
- Substances with high heat capacity can store a lot of thermal energy.
- Metals are good conductors of heat, while water is useful for storing thermal energy.
- Heat capacity, specific heat capacity, and molar heat capacity can be calculated using the equations Q = mcΔT and Q = nCΔT.
