Determine how much kerosene you need to burn to get the amount of heat

Determine how much kerosene you need to burn to get the amount of heat Q = 4.6 * 10 ^ 7? Specific heat of combustion of kerosene q = 43.1 MJ / kg

To find the required mass of kerosene, we use the formula: m = Q / q, where Q is the amount of heat obtained from burning the taken kerosene (Q = 4.6 * 10 ^ 7 J = 46 * 10 ^ 6 J); q is the specific heat of combustion of kerosene (according to the condition q = 43.1 MJ / kg = 43.1 * 10 ^ 6 J / kg).

Let’s calculate: m = 46 * 10 ^ 6 / (43.1 * 10 ^ 6) = 1.067 kg.

Answer: To obtain 4.6 * 10 ^ 7 J of heat, you will need to burn 1.067 kg of kerosene.
