What you need to know
- Specific heat capacity is the energy needed to raise the temperature of 1 kg of a substance by 1 °C.
- The change in thermal energy equals mass multiplied by specific heat capacity multiplied by temperature change.
- Heating 2 kg of water from 20 °C to 100 °C needs 672,000 J, showing that energy depends on mass as well as temperature change.
- The equation can be rearranged, for example to find the mass of water in a cooling hot water bottle.

As reported by YouTube on 2026-11-02. Not part of the Heddy Score.Why we picked it
Worked examples show that the energy stored depends on mass and material, not on temperature alone.
