Frequently Examined
Specific latent heat is a popular calculation topic. Common exam scenarios:
- Calculation: E = mL (2-3 marks): Given mass and L, find energy. Or rearrange to find mass. Always show working and include units (J).
- Explain why Lv > Lf (3 marks): Link to bond-breaking — melting loosens bonds (particles stay close), boiling completely breaks all bonds (particles separate fully).
- Explain why temperature stays constant (3 marks): Energy → breaking bonds → potential energy increases, kinetic energy unchanged → temperature unchanged.
- Steam vs boiling water context question (2 marks): Steam releases latent heat of vaporisation when it condenses, giving more total energy transfer to skin.
