WebThe average kinetic energy of those particles — the moving energy — is temperature. Heat and temperature are different. Heat energy can flow between substances when there is a constant temperature, also known as latent heat. Heat content is often measured in British thermal units (Btu). A Btu amount reflects fuel and energy source heat content. Web2 apr. 2024 · You are told that the change of internal energy is Δ U = 34 J − 27 J = 7 J, so the overall energy of the system has increased. Also, the system does 26 J of work. As said before, work done by the system decreases it's energy. So in the end, you have 7 J more in your system than before, but you have also taken out 26 J of energy. heating load rule of thumb
