Exam points
- Define specific heat capacity as the energy needed to raise the temperature of 1 kg of a substance by 1 °C or 1 K; use the unit J/(kg °C).
- For similar energy transfer to equal masses, explain differences in temperature change using the materials’ specific heat capacities.
- For the same heater power, explain how a temperature-time graph gradient depends on the material’s specific heat capacity and state.
