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 key 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? Supplying the specific latent heat to $1$ kg of ice at $0$ °C makes its temperature rise.

False. It melts the ice at $0$ °C with no temperature change.
