Latent heat equation

E = mL

What is latent heat?

Energy needed to change state without changing temperature. 'Latent' = hidden.

Sample Questions

What is specific latent heat?

A. The energy needed to raise 1 kg of a substance by 1 °C
B. The energy needed to change the state of 1 kg of a substance without changing its temperature
C. The temperature at which a substance changes state
D. The rate of energy transfer during a state change

1 markfoundation

During a state change, energy is being supplied to a substance but the temperature does not change. Explain where this energy goes.
