TL;DR
SEAB’s 2026 6091 syllabus calls out energy-transfer investigations, heat-capacity measurements, and latent-heat determinations as recurring Paper 3 tasks (SEAB syllabus PDF).
Planning marks emphasise insulation strategy, control variables (initial temperature, mass, heating duration), and quantified safety precautions.
ACE marks depend on energy-balance calculations, justified assumptions (no heat loss, constant specific heat), and realistic improvements such as better insulation or stirrer upgrades.

Investigation focus	Key measurements	Typical sources of error
Energy transfer comparison	Initial and final temperatures, mass of medium, timing of heating/cooling phases.	Heat loss to surroundings, thermometer response time, uneven surface finish between test samples.
Heat capacity of solids	Heater voltage/current, heating duration, mass of sample, temperature rise.	Poor thermal contact, inaccurate electrical power, unnoticed heat losses during transfer.
Latent heat (fusion/vapour)	Mass change (melted solid/condensed steam), heater input or energy absorbed/released.	Heat loss during transfer, steam escaping, mass readings affected by water droplets on balance pan.
