AQQ GCSE Physics Changes of state and specific latent heat

What is the energy needed for a substance to change its state called?
Do five star jumps.
When a change of state occurs, the energy supplied changes the energy stored (internal energy). What is not changed.
Sketch a heating curve for water. Temperature against energy supplied.
Define the specific latent heat of a substance.
Look at this equation.
What is the unit for mass?
What is the unit for specific latent heat?
What is the unit of energy for a change of state?
Rearrange the equation so that m = and L =
What does the L refer to?
Define the specific latent heat of fusion.
Define the specific latent of vaporisation.
Spend twenty minutes on your Nintendo switch.
Sketch a heating curve and a cooling curve and label where the changes of state occur.
Why are the regions on the graph where there is a change of state flat?
What is the difference between specific heat capacity and specific latent heat?
