Answer to Question #15531 in Molecular Physics | Thermodynamics for david worsley

Question #15531
If you placed a rubber baloon (not blown up but sealed) containing water into a pressurised steel vessel with liquid in the bottom half , would the `baloon` be affected by changes in the pressure, ie from vacuum to positive pressure.Would it change shape and would there be any pressure change within the baloon? Your help would be appreciated.
Expert's answer
We placed the rubber balloon into the vessel and change the pressure from
vacuum to positive pressure.So, 1st the liquid start evaporates because boiling
point depends on the pressure (p*V/T=constant,when
p-pressure,V-volume,T-temperature for gas) , so in a vacuum it can not break
from compensated pressure water that evaporated. Nevertheless if he survive,
then apply pressure water begins to condense.
