6.3.2.2 Temperature changes in a system and specific heat capacity
| Content | Key opportunities for skills development |
|---|---|
If the temperature of the system increases: The increase in temperature depends on the mass of the substance heated, the type of material and the energy input to the system. | |
The following equation applies: |
change in thermal energy, ΔE, in joules, J
mass, m, in kilograms, kg
specific heat capacity, c, in joules per kilogram per degree Celsius, J/kg °C
temperature change, ∆θ, in degrees Celsius, °C.
The specific heat capacity of a substance is the amount of energy required to raise the temperature of one kilogram of the substance by one degree Celsius.
MS 1a, 3b, 3c, 3d Students should be able to apply this equation, which is given on the Physics equation sheet, to calculate the energy change involved when the temperature of a material changes. This equation and specific heat capacity are also included in Energy changes in systems (page 123). |
