April 11, 2021 | education
| Given:
m (mass of coal) = 15 kg.
q (specific heat of combustion of coal) = 2.7 * 10 ^ 7 J / kg.
Decision:
Calculation formula: Q = q * m.
Let’s perform the calculations: Q = 2.7 * 10 ^ 7 * 15 = 40.5 * 10 ^ 7 J = 405 MJ.
Answer: With the complete combustion of 15 kg of coal, 405 MJ of thermal energy will be released.
