What amount of work is equivalent to the amount of heat obtained from the combustion of 1 kg of coal? specific heat of combustion of coal is 29.9 * 10 to the 6th degree J / kg
The energy of the burnt coal: E = m * λ => E = 29.9 * 10 ^ 6 J / kg * 1 kg = 29.9 * 10 ^ 6 J. Thermal energy is also energy. Energy is work. Therefore, A = E = 29.9 * 10 ^ 6 J.
Answer: 29.9 * 10 ^ 6 J.
