S1 Science: Heat and Temperature – Conduction, Convection, Radiation and the Vacuum Flask (Paper 1: basics)
Paper one starts with temperature, heat and the three heat paths, sorting the vocabulary first.
Direct answers Remember one line: separate heat from temperature, then separate conduction, convection and radiation.

03 Answers and one-line notes
| # | Answer | One-line note |
|---|---|---|
| 1 | No: temperature tells how hot, heat is energy transferred, measured in joules. | Temperature is read on a thermometer; heat is energy in joules. |
| 2 | It rises by 40 C. | 60 minus 20 gives 40. |
| 3 | The metal spoon, because metal is a good conductor. | Metal has free electrons, so it carries heat far faster than wood. |
| 4 | Hot water is less dense, so it floats up and sets up a convection current. | Heating makes water expand and lose density, so cooler water sinks to take its place. |
| 5 | No, it travels through a vacuum. | Heat from the Sun reaches Earth through space, which is radiation. |
| 6 | 42 000 J. | 0.5 times 4200 times 20 gives 42 000 J. |
| 7 | 378 000 J, that is 378 kJ. | 1.5 times 4200 times 60 gives 378 000 J. |
| 8 | It releases 4 680 J. | 0.2 times 390 times 60 gives 4 680 J. |
| 9 | About 63 seconds, a little over a minute. | 1 times 4200 times 30 gives 126000 J, divided by 2000 is 63 seconds. |
| 10 | Metal is a good conductor, so it conducts fast and heats up quickly. | Slow conductors are insulators such as wood, plastic and foam. |
04 What to do after marking
- After marking, redo only the wrong items and write down which step went wrong (formula, unit, or misread number).
- Repeat the same item two days later; move to the next paper only when both attempts are correct.
- Parents only need the answer and note columns; there is no need to explain every item.
After paper one, take paper two and get comfortable with specific heat capacity and flask design.Tutor Registration →
