Changes in Energy (AQA GCSE Physics Combined Science): Flashcards

Energy to raise 1 kg of material by 1°C

J/kg°C

$c$

thermal energy to increase temperature

$\Delta E = m \times c \times \Delta\theta$

Change in thermal energy (J)

Mass (kg)

Change in temperature (°C or K)

4,200 J/kg°C

$P = V \times I$

$E = P \times t$

$c = \frac{\Delta E}{m \times \Delta\theta}$

High specific heat capacity - absorbs lots of heat without large temperature increase

Low specific heat capacity
