P1.2.4 - Specific latent heat Flashcards
1
Q
What is the specific latent heat of fusion?
A
It is the energy transferred when 1kg of a substance changes from the solid to liquid state or liquid to solid state.
2
Q
What is the specific latent heat of vaporisation?
A
It is the energy transferred when 1kg of a substance changes from liquid to gas state
3
Q
How do you work out specific latent heat?
A
Thermal energy for a change in state = mass x specific latent heat
4
Q
What is the difference between specific latent heat from specific heat capacity?
A
Latent heat is about the change of state and specific heat capacity is about the change of temperature
