With the complete combustion of TNT weighing 10 kg, 1.5 * 10 ^ 8J of energy was released. What is the specific heat of combustion of TNT?

Problem data: m (mass of burnt TNT (trinitrotoluene)) = 10 kg; Q (released thermal energy) = 1.5 * 10 ^ 8 J.

To find the specific heat of combustion of TNT, we apply the formula: qt = Q / m.

Let’s calculate: qt = 1.5 * 10 ^ 8/10 = 15 * 10 ^ 6 J / kg (15 MJ / kg).

Answer: TNT, according to the calculation, has a specific heat of combustion of 15 MJ / kg.
