Heat and Temperature Practice
Use “temperature” for average particle kinetic energy and “heat transfer” for energy moving between regions because of a temperature difference.
Learning objective
A printable worksheet on particle motion, transfer and conductors.
Questions
1. Explain why a metal spoon feels colder than a wooden spoon in the same room.
2. Name conduction, convection or radiation for energy from the Sun to Earth.
3. Design a fair comparison of two cup materials for keeping water warm.
4. Why does warm air rise in a room?
Answer section
- 1. Metal conducts energy away from your hand faster; both objects may have the same temperature.
- 2. Radiation.
- 3. Use equal water volumes and starting temperatures, identical lids and measure temperature at fixed times.
- 4. Heating makes air expand and become less dense, so it rises while cooler air moves in.
Check your method: An answer is stronger when the working, unit, diagram or explanation makes the choice visible.
