| January 4, 2021 | education
To find the heat released during the combustion of 4 kg of taken coal, we apply the formula: Q = m * qku.
Constants and variables: m – mass of taken coal (m = 4 kg); qku – beats heat of combustion of coal (qku = 27 * 10 ^ 6 J / kg).
Calculation: Q = m * qku = 4 * 27 * 10 ^ 6 = 108 * 10 ^ 6 J.
Answer: When burning 4 kg of taken coal, 108 MJ of heat should be released.
