What amount of heat will be released during the complete combustion of alcohol weighing 300 g?
| April 5, 2021 | education
The amount of heat that will be released during the combustion of 300 g of alcohol is calculated using the formula:
Q = q * m, where q is the specific heat of combustion of alcohol (let us assume q = 2.7 * 10 ^ 7 J / kg), m is the mass of burned alcohol (m = 300 g = 0.3 kg).
The released amount of heat is equal to:
Q = q * m = 2.7 * 10 ^ 7 * 0.3 = 8.1 * 10 ^ 6 = 8.1 MJ.
Answer: When 300 g of alcohol is burned, 8.1 MJ of heat will be released.
