WebNov 15, 2009 · It's a unique property of ideal gases that [itex]\Delta U=mC_V\Delta T[/itex] holds for any process. The constant-volume constraint is not required. That's why I also wrote the equation as [itex]\Delta U=m(C_P-R)\Delta T[/itex], which similarly doesn't mean that constant pressure is required just because the constant-pressure specific heat appears. WebSep 30, 2015 · Δ U = Q + W where Q is amount of heat transferred to the system and W is work done on the system. Since the process is adiabatic, no heat is transferred into or out of the system, i.e. Q = 0 and thus Δ U = W The reversible expansion is performed continuously at equilibrium by means of infinitesimal changes in pressure p.
