WebAug 14, 2024 · The relationship between the energy change of a system and that of its surroundings is given by the first law of thermodynamics, which states that the energy of the universe is constant. We can express this law mathematically as follows: Uuniv = ΔUsys + ΔUsurr = 0. ΔUsys = − ΔUsurr. where the subscripts univ, sys, and surr refer to the ... WebThe first law of thermodynamics states that the change in internal energy of a closed system equals the net heat transfer into the system minus the net work done by the system. In equation form, the first law of thermodynamics is. Δ U = Q − W. 12.6. Here, Δ U is the change in internal energy, U, of the system.
