The energy required to heat a product can be calculated as
q = cp m dt (1)
where
q = heat required (kJ)
cp = specific heat (kJ/kg K, kJ/kg oC)
dt = temperature difference (K, oC)Example - Required Heat to increase Temperature i Water
10 kg of water is heated from 20 oC to 100 oC - a temperature difference 80 oC (K). The heat required can be calculated as
q = (4.19 kJ/kg K) (10 kg) (80 oC)

See also tabulated values of specific heat of Gases, Food and foodstuff, Metals and semimetals, Common solids and other Common substances.Heating Energy
The energy required to heat a product can be calculated as
q = cp m dt (1)
where
q = heat required (kJ)
cp = specific heat (kJ/kg K, kJ/kg oC)
dt = temperature difference (K, oC)Example - Required Heat to increase Temperature i Water
10 kg of water is heated from 20 oC to 100 oC - a temperature difference 80 oC (K). The heat required can be calculated as
q = (4.19 kJ/kg K) (10 kg) (80 oC)
= 3352 kJ Related Topics
