Specific Latent Heat Flashcards
1
Q

A
When energy is being transferred or lost (breaking or making bonds) but not being used to change the temp.
2
Q

A
The amount of Energy needed to change 1Kg of a substance
3
Q

A
between a solid and liquid (melting or freezing)
4
Q
What is the specific Latent heat of vaporisation?
A
Changing between Liquid and Gas
5
Q
Formula for specific Latent Heat?
A
Energy (E) = Mass (m) x Specific Latent Heat (L)
E = Joules
m = Kg
L = J/Kg
