In thermodynamics, the concept of changes in volume causing work refers to the principle that when a system undergoes a change in volume, work is performed. Work done by the system can occur when there is a gaseous expansion or compression, resulting in a change in the system's volume. This work is a manifestation of energy transfer and is quantified as the product of the force applied to the boundary of the system and the displacement of that boundary. In summary, changes in volume cause work in thermodynamics as a result of the energy transfer associated with the expansion or compression of a system.
