univerkov | July 28, 2021 | education

Initial data: m (mass of burned gasoline) = 2 kg.

Reference values: q (specific heat of combustion of gasoline) = 44 MJ / kg (44 * 10 ^ 6 J / kg).

The required amount of released heat is equal to the product of the mass of gasoline and its specific heat of combustion: Q = q * m.

Calculation: Q = 44 * 10 ^ 6 * 2 = 44 * 10 ^ 6 * 2 = 88 * 10 ^ 6 J (88 MJ).

Answer: c) when burning 2 kilograms of gasoline, 88 MJ of heat is released.
