Heating and cooling curves
Heating and cooling curvesFree1:12Heddy Score 3 of 7, below the standard
What you need to know
- When ice at -10 °C is heated, its temperature rises until it reaches 0 °C.
- While it melts the temperature stays at 0 °C because the energy supplied is changing its state, not raising its temperature.
- The water then warms to 100 °C and stays at that temperature while it boils.
- The energy needed to change state is the mass multiplied by the specific latent heat, which differs for melting and for boiling.
