First law of thermo equation
WebSep 13, 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. Using Equation 18.1.1, we can express this law mathematically as follows: (18.2.1) Δ E u n i v = Δ E s y s + Δ E s u r r = 0. Δ E s y s = − Δ E s u r r.
