Specific latent heat Flashcards
1
Q
What is specific latent heat?
A
The specific latent heat of a substance is defined as the energy required to change the phase per unit mass while at a constant temperature.
2
Q
What is SLH of fusion?
A
Solid -> Liquid
3
Q
What is SLH of vaporisation?
A
Liquid -> Gas
4
Q
How do you determine SLH of fusion?
A
- Thermoeter to ensure ice is at melting point
- Measure V, I and time during which the heater was used
- E = IVt
- Measure mass of ice used then use L = (IVt)/m
