📖 Key Definitions
Specific heat capacity (c): The energy required to raise the temperature of 1 kg of a substance by 1°C. Units: J/kg°C.
Temperature change (Δθ): The difference between the final and initial temperatures. Δθ = θ_final − θ_initial. Units: °C (or K for identical numerical value).
Thermal capacity: The total energy needed to raise the temperature of an object by 1°C. Equals mass × SHC. Units: J/°C.
Thermal equilibrium: The state where two objects in contact have reached the same temperature and there is no net flow of heat between them.

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.
