Energy changes in systems (AQA GCSE Physics): Quizzes

Energy to heat 1 kg by 1°C

4200 J/kg°C

$\Delta E = mc\Delta\theta$

Change in thermal energy in joules

Water

J/kg°C

90,000 J

60°C

To reduce energy loss to surroundings

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

It has a high specific heat capacity
