a container contains....

None

A container contains 10 ml of H2O in an initially evacuated container of vol 1lt.press exte is then suddenly reduced to 0 such that the undergoes free expansion till all lqd is just evaporated. temp is kept const =300k by a source of heat in the container if Q supplied in 2 entire is 30KJ & final vol is 5lt then calcul change in E,H of the process & change in standard enthalpy of vapourisation.
aques. tension of H2O at 25 degree C =25 mm of Hg density of water =1 gm/cc
