Mixed with 2 kg of gasoline and 3 kg of kerosene. how much heat will be released during the complete combustion of the resulting fuel.
To find the amount of heat that should have been released during the complete combustion of the created fuel, we apply the formula: Q = qb * mb + qk * mk.
Constants and variables: qb – heat of combustion of gasoline (qb = 4.6 * 10 ^ 7 J / kg); mb is the mass of gasoline in the mixture (mb = 2 kg); qk is the heat of combustion of kerosene (qk = 4.6 * 10 ^ 7 J / kg); mk is the mass of kerosene in the mixture (mk = 3 kg).
Calculation: Q = qb * mb + qk * mk = 4.6 * 10 ^ 7 * 2 + 4.6 * 10 ^ 7 * 3 = 230 * 10 ^ 6 J (230 MJ).
Answer: 230 MJ of heat will be released.
