How is energy transferred calculated

WebA reaction or process in which heat is transferred to a system from its surroundings is endothermic. The first law of thermodynamics states that the energy of the universe is constant. The change in the internal energy of a system is the sum of the heat transferred and the work done. Web20 feb. 2024 · Calculate the temperature from the heat transferred using Q = Mgh and ΔT = Q mc, where m is the mass of the brake material. Insert the values m = 100kg and c = 800J / kg ⋅oC to find ΔT = (7.35v × 106J) (100kg)(800J / kgoC) = 92oC. Discussion This temperature is close to the boiling point of water.
