Answer Posted / ibrahim_mahmoud

expansion of a high pressure gas or vapor that vapor is
inside an insulated vessel or container and the heat content
of that vapor before expansion is the same heat content
after expansion , the pressure will be less due to expansion
and the volume will be bigger after expansion
h=constant (enthalpy: heat content)
V1<V2 (Volume)
P2<P2 ( pressure)
i am not sure of the pressure
sorry
