| September 9, 2021 | education
Initial data: m (mass of burnt kerosene) = 3 kg.
Reference data: q (specific heat of combustion of kerosene) = 46 MJ / kg = 46 * 10 ^ 6 J / kg.
The amount of heat that the primus will emit is calculated by the formula: Q = q * m.
Let’s do the calculation:
Q = 46 * 10 ^ 6 * 3 = 138 * 10 ^ 6 J = 138 MJ.
Answer: In an hour, the primus will emit 138 MJ of heat.
