Changes in Energy (OCR GCSE Physics A, Combined (Gateway Science Suite)): Flashcards

Temperature increases

Energy to raise 1 kg of material by 1°C

Lowercase $c$

J/kg°C

More energy needed to increase temperature

Less energy needed to increase temperature

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

Change in thermal energy (J)

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 SHC - absorbs heat without large temp increase

Low specific heat capacity
