Acolumn was used to strip low-volatile materials from a high-temperature heat transfer fluid. during a maintenance procedure, water was trapped between two valves. during normal operation, one valve was opened and the hot oil came in contact with the cold water. the result was almost sudden vaporization of the water, followed by considerable damage to the column. consider liquid water at 5°c and 0.5 atm.
how many times does the volume increase if the water is vaporized at 100 °c and 0.5 atm?
