Hi Knowledgeable folks,
Since boiling point of a liquid can be reduced via pressure reduction. I was wondering whether this is possible: Add some liquid (alcohol or Water) in a container, reduce the pressure inside the container so that, say the liquid inside can boil at say 10 degree Celsius (50 degree Fahrenheit) and seal the container air-tight. Now if I insulate the container well and at the top of the container place a cooling device (peltier, ice, chill water - which can produce say 5 degree Celsius/41 degree Fahrenheit cooling). Will/Can the water/alcohol inside the container freeze?. I was thinking since the container has low pressure and if he vapor inside can be condensed repeatedly using cooling - which will vacuum and the liquid inside can boil and get frozen - is it possible (would be a easy refrigerator) - since now one has done this perhaps there is something that I must be missing and wanted to know what that is.
Thanks a lot for your time and sharing.
