Problem data: m (mass of burned gasoline) = 1500 g (in SI m = 1.5 kg).

Reference values: qb (specific heat of combustion of gasoline) = 4.6 * 10 ^ 7 J / kg.

The thermal energy obtained from the combustion of 1500 g of gasoline is calculated by the formula: Q = qb * m.

Let’s calculate: Q = 4.6 * 10 ^ 7 * 1.5 = 6.9 * 10 ^ 7 J (69 MJ).

Answer: When 1500 g of gasoline is burned, 69 MJ of thermal energy will be released.
