Specific Heat & Latent Heat Flashcards

All 4 cards in this deck

Define specific heat capacity.: The energy needed to raise the temperature of 1 kg of a substance by 1 °C.
Define specific latent heat.: The energy needed to change the state of 1 kg of a substance, with no change in temperature.
What is the difference between specific heat capacity and specific latent heat?: Specific heat capacity involves a temperature change with no change of state; specific latent heat involves a change of state at constant temperature.
True or false? Specific heat capacity is measured in J/kg.: False. Specific heat capacity is measured in J/kg °C; J/kg is the unit of specific latent heat.
