Latent Heat Practical for O-Level Physics Paper 3
A focused O-Level Physics 6091 Paper 3 guide to latent heat practicals, energy readings, heat loss, mass change, and evaluation language.
The core idea is simple: Latent heat practicals are about energy during a change of state.
Use it as a working check: Watch the mass change, electrical energy input, and heat loss to surroundings.
Then go one layer deeper: In Paper 3, the mark-winning answer is not only a formula. It connects readings, assumptions, heat loss, and the direction of the final error.
The SEAB O-Level Physics 6091 syllabus lists latent heat of substances among possible Paper 3 practical areas. This focused guide sits beside the O-Level Physics Thermal Practical Handbook and the specific heat capacity experiment guide.
Use the O-Level Physics practical hub if you need the wider Paper 3 pathway.
What Makes Latent Heat Different
Specific heat capacity practicals involve a temperature change. Latent heat practicals involve a change of state. During the change of state, the energy supplied changes internal energy without a temperature rise.
That difference affects the practical:
- the mass before and after the change matters;
