WebSep 16, 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
WebAn open system can exchange both matter and energy with its surroundings. A pot of boiling water is an open system because a burner supplies energy in the form of heat, and matter in the form of water vapor is lost as the water boils.
