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. WebIn the formula the negative sign indicate that the pressure of gas that is in the system is working against the external pressure . the external pressure could be block or anything …
