What is specific heat capacity?
Show answer
Some materials heat up easily, others need a lot of energy. The specific heat capacity, cc, is the energy needed to raise the temperature of one kilogram of a substance by one degree Celsius.
What is latent heat?
Show answer
The energy needed to change the state of a substance without changing its temperature is called latent heat ("latent" means hidden):
