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

Energy to raise 1 kg of a material by 1°C

J/kg°C

Lowercase c

$ΔE = m × c × Δθ$

Change in thermal energy (J)

Mass of the object (kg)

Specific heat capacity (J/kg°C)

Change in temperature (°C or K)

Requires more energy to increase temperature

Needs less energy to increase temperature

$P = V × I$

$E = P × t$

$c = \frac{ΔE}{m × Δθ}$

High specific heat capacity absorbs lots of heat without large temperature rise

Low specific heat capacity
