Heat Required for Temperature Change
Q = m × s × Δt
SymbolMeaningUnit
QHeat suppliedJ
mMasskg
sSpecific heat capacityJ/(kg K)
ΔtTemperature changeK or °C
Worked example
Given: m = 2 kg, s = 4200 J/kg K, Δt = 5 K Calculation: Q = 2 × 4200 × 5 Answer: Q = 42000 J
Thermal Capacity
C = m × s
SymbolMeaningUnit
CThermal capacityJ/K
mMasskg
sSpecific heat capacityJ/(kg K)
Worked example
Given: m = 2 kg, s = 500 J/kg K Calculation: C = 2 × 500 Answer: C = 1000 J/K
Latent Heat
Q = m × L
SymbolMeaningUnit
QHeat absorbed or releasedJ
mMasskg
LSpecific latent heatJ/kg
Worked example
Given: m = 0.5 kg, L = 334000 J/kg Calculation: Q = 0.5 × 334000 Answer: Q = 167000 J
Principle of Calorimetry
Heat lost = Heat gained
SymbolMeaningUnit
QlostHeat lostJ
QgainedHeat gainedJ
Worked example
Given: Hot and cold bodies exchange heat in an insulated vessel Calculation: Heat lost = Heat gained Answer: Set both heat expressions equal.
