What does specific heat capacity (c) refer to?

How well a substance stores heat

Definition of specific heat capacity

Energy needed to raise 1 kg of substance by 1°C

Formula for change in thermal energy

ΔE=m×c×Δθ\Delta E = m \times c \times \Delta \theta

Symbol and unit for change in thermal energy

ΔE\Delta E, joules (J)

Symbol and unit for specific heat capacity

cc, J/kg°C

Symbol and unit for mass in the formula

mm, kilograms (kg)

Symbol and unit for temperature change

Δθ\Delta \theta, degrees Celsius (°C)

Rearranged formula to find specific heat capacity

c=ΔEm×Δθc = \frac{\Delta E}{m \times \Delta \theta}

What does change in thermal energy depend on?

Mass, specific heat capacity (material), and temperature change
