Answer 2

Calculating Heat Release from Fuel Combustion

To calculate the heat release from the complete combustion of the given fuel mixture, we can use the formula:

Q = m * c * ΔT

Where: - Q = heat released - m = mass of the fuel - c = specific heat capacity of the fuel - ΔT = change in temperature

Specific Heat Capacities of Gasoline and Kerosene

The specific heat capacities for gasoline and kerosene are not provided in the search results. However, for the purpose of this calculation, we can use the average specific heat capacity of gasoline, which is approximately 2.2 kJ/g°C, and the specific heat capacity of kerosene, which is approximately 2.1 kJ/g°C.

Calculation

Given: - Mass of gasoline (m1) = 2 kg - Mass of kerosene (m2) = 3 kg - Specific heat capacity of gasoline (c1) = 2.2 kJ/g°C - Specific heat capacity of kerosene (c2) = 2.1 kJ/g°C

We can calculate the total heat release (Q) from the combustion of the fuel mixture using the formula:

Q = (m1 * c1 + m2 * c2) * ΔT

Conclusion

The specific heat capacities of gasoline and kerosene are essential for accurately calculating the heat release from their combustion. If the specific heat capacities are available, the calculation can be performed using the provided formula.
