Delta v thermodynamics

WebIn Mathematics, δ and Δ essentially refer to the same thing, i.e., change. This means that Δ x = x 1 − x 2 = δ x. The difference between δ and d is also clear and distinct in differential calculus. We know that d y d x is always an operator and not a fraction, whereas δ y δ x is an infinitesimal change. In Physics, however, the ... WebJan 5, 2014 · If you have an ideal gas in a constant volume adiabatic chamber, with the gas initially occupying only half the chamber, and vacuum in the other half, with a barrier in between, and you remove the barrier and then let the system re-equilibrate (i.e., free expansion), the work done on the system will be zero (rigid container) and $\Delta U = 0$.
