⚙️ How It Works: Energy, Temperature, and Particles
Temperature measures the average kinetic energy of particles. When you supply energy to a material, the particles speed up and vibrate more vigorously. But the amount of temperature rise per joule depends on how many particles there are and how strongly they interact.
Water molecules interact strongly with each other through hydrogen bonds. These bonds absorb a lot of energy before the molecules gain enough kinetic energy to raise the temperature noticeably. This is why water has such a high SHC — much of the energy input goes into stretching these bonds rather than increasing the average particle speed directly.
In metals, conduction electrons can distribute thermal energy rapidly, but the atomic structure means less energy is needed per degree of temperature rise. Hence metals have low SHC and heat up quickly.

Practice Questions for Specific Heat Capacity
What does the specific heat capacity of a substance measure?
Water has a specific heat capacity of 4200 J/kg°C, much higher than most other common substances. Explain why this makes water useful in central heating systems.
