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 latent heat of fusion and specific latent heat of vaporisation?

Fusion is for melting/freezing (solid ↔ liquid); vaporisation is for boiling/condensing (liquid ↔ gas).

True or false? Specific heat capacity and specific latent heat are both measured in J/kg °C.

False. Specific heat capacity is in J/kg °C; specific latent heat is in J/kg.
