The specific heat of a substance can be used to calculate the temperature change that a given substance will undergo when it is either heated or cooled. The equation that relates heat (q) (q) to specific heat (cp) (c p), mass (m) (m), and temperature change (ΔT) (Δ T) is shown below. q = cp × m × ΔT q = c p × m × Δ T.

13 Μαΐ 2023 · The heat capacity (C) of a body of matter is the quantity of heat (q) it absorbs or releases when it experiences a temperature change (ΔT) of 1 degree Celsius (or equivalently, 1 kelvin) C = q ΔT. Heat capacity is determined by both the type and amount of substance that absorbs or releases heat.
6 Μαρ 2024 · Example Calculation. For instance, calculate the heat required to raise the temperature of 2 kg of water from 20°C to 100°C: Given: m = 2 kg (mass of water), c = 4.186 kJ/kg°C (specific heat capacity of water), ΔT = 100°C − 20°C =80°C; The heat Q required is: Q = 2 kg × 4.186 kJ/kg°C × 80°C = 669.76 kJ
