Isothermal process from compressed liquid zone to superheated vapour zone on PV diagram for water with proper labeling
Answers
Answer:
If we heat ice at different vapor pressures and note down the corresponding change in volumes, the saturation state points for solid, liquid and vapor (state from which a change of phase may occur without change of pressure and temperature) for different pressures may be obtained on a p-V diagram.
By joining the saturated solid states at various pressures, a saturated solid line ‘ECA’ is obtained. Similarly, by joining all the saturated liquid states with respect to solidification and by joining all the saturated liquid states with respect to vaporization, saturated liquid lines ‘FG’ and ‘HG’ are obtained. Finally, by joining all the vapor states at various pressures saturated vapor line ‘HB’ is obtained and a phase equilibrium diagram of water on p-v co-ordinates will
