How to solve for energy
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. WebDec 9, 2013 · The energy of the system has changed, even if the starting and ending kinetic energies are the same.
