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

Energy to raise 1 kg by 1°C

J/kg°C

More thermal energy needed to raise temp

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

Change in thermal energy (J)

Change in temperature

4,200 J/kg°C

84,000 J

Ammeter

To minimize heat loss

$P = V \times I$

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