Changes in Energy (OCR GCSE Physics A (Gateway Science Suite)): Quizzes

Energy to raise 1 kg by 1°C

J/kg°C

$c$

More thermal energy to increase temp

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

Change in thermal energy (J)

Change in temperature (°C or K)

84,000 J

To minimise heat loss

$P = V \times I$

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

High SHC - absorbs heat without big temp rise
