O-Level Physics Thermal Practical Handbook (Energy Transfer & Calorimetry)
Study guide
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.

1 | Thermal experiments highlighted by SEAB
- Item 7 requires you to investigate factors affecting energy transfer through conduction, convection, or radiation - expect comparative setups (shiny vs dull, thick vs thin insulation) (SEAB 6091 syllabus PDF).
- Items 8 and 9 cover calorimetry routines: determining heat capacities and latent heat of substances, often via electrical heating coils or steam condensation (same source).
- Thermal tasks commonly embed partial planning prompts, so rehearse variable identification, insulation controls, and risk commentary (hot water, electrical heaters).
| 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. |

Practical course completion-record note
For practical, lab, and experiment courses, Eclat Institute maintains centre-held attendance records and may also issue an internal attendance or completion document based on participation and internal assessment.
- For SEAB private-candidate declarations, the key evidence is the centre's attendance or completion record, not a government-issued certificate.
- This is an internal centre-issued certificate, not an MOE/SEAB qualification or accreditation.
- Recognition (if any) is determined by the receiving school, institution, or employer.
- For SEAB private candidates taking science practical papers, SEAB states you should either have taken the subject before or attend a practical course and complete it before the practical paper date.
