The amount of energy supplied to it.

The mass of the substances.

What the substance is.
What is the specific heat capacity?
The energy needed or energy transferred to 1kg of the substance to raise its temperature by 1°C. The unit is the joule per kilogram degree Celsius (J/(kg°C)).
What is latent heat?
The energy supplied to a substance when it changes state. The temperature does not change at the melting point or the boiling point until the substance has changed state.

This is because the energy is used by particles to break free from each other.
What is the specific latent heat?
The energy needed to melt 1kg of the substance at its melting point or to change 1kg of the substance at its boiling point from liquid to vapour. The unit is the joule per kilogram (J/kg).
