The specific heat capacity of a substance is the quantity of thermal energy required to raise the temperature of 1 g of the substance by 1°C
Calorimetry is the experimental process of measuring the thermal energy change in a chemical or physical change.
Q = m c Δ T
Q = quantity of energy absorbed/released (J)
m = mass (g)
c = specific heat capacity (J/g°C)
ΔT = change in temperature
water: 4.18 J/g°C
