A truck on the way of 100 km used up gasoline weighing 20 kg. How much heat can be released when this mass of gasoline is burned?
Problem data: m (mass of gasoline consumed by the truck) = 20 kg.
Reference values: q (specific heat of combustion of motor gasoline) = 44 * 10 ^ 6 J / kg.
The amount of heat released from the combustion of 20 kg of gasoline is calculated by the formula: Q = q * m.
Calculation: Q = 44 * 10 ^ 6 * 20 = 880 * 10 ^ 6 J (880 MJ).
Answer: When 20 kg of motor gasoline is burned, 880 MJ of heat will be released.
