A
The energy required to heat up 1kg of a substance by 1K
2
Q
Specific latent heat of fusion
A
The amount of heat energy required per unit mass, to change a substance from a solid to a liquid without any change in temperature.
3

Q
Boyles law
A
- Assume constant temperature
- Volume is inversely proportional to pressure
- Pv = k
5
Q
Charles law
A
- Assume that pressure is constant
- Volume is directly proportional to temperature
