| February 12, 2021 | education
Formula for calculating the calorific value:
Q = qm.
q – specific heat of combustion, J / kg.
m – weight, kg.
Specific heat of combustion is a tabular value and is equal to 10.2 MJ / kg for pine.
m = 2 kg.
Q = 10.2 × 10 ^ 6 J / kg × 2 kg = 20.4 × 10 ^ 6 J = 20.4 MJ.
Answer: the amount of heat generated during the combustion of pine wood is 20.4 MJ.
