WebThe first law of thermodynamics, or the law of conservation of energy. The change in a system’s internal energy is equal to the difference between heat added to the … WebConclusions. Work is the energy required to move something against a force. The energy of a system can change due to work and other forms of energy transfer such as heat. Gases do expansion or compression work following the equation: work = − P Δ V. \text {work} = -\text P\Delta \text V work = −PΔV.
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 ...
