Bruce Tuncks Posted December 11, 2019 Share Posted December 11, 2019 Gosh litespeed, I don't like my beer as cold as you do. Nev, you can have liquid CO2 but not at one atmosphere. CO2 has this property in common with other refrigerant substances. You condense it to a liquid at high pressure and say 40 degrees, then you let it boil at -17 degrees and say 1 atmosphere. Separating the 2 different pressure regions is the expansion valve. The compressor makes it move. When it boils, it absorbs heat and this keeps your beer cold, if some of the heat required comes from your warm beer. 1 1 Link to comment Share on other sites More sharing options...
Bruce Tuncks Posted December 11, 2019 Share Posted December 11, 2019 Here's an experiment to try on the moon. Put out a bowl of liquid water. It will boil instantly and what is left will be ice, which will sublimate until its gone. Bugger, my Jab won't get me there. 1 Link to comment Share on other sites More sharing options...
onetrack Posted December 11, 2019 Share Posted December 11, 2019 I've got a friend who lives in Lynn Lake Manitoba, where it occasionally gets to -30ºC, and even lower. He likes showing us the stunt of throwing boiling water into the air into these temperatures, whereby it instantly turns into chunks of ice, as it falls. https://www.nationalgeographic.com/news/2018/01/frozen-bubbles-boiling-water-freezing-explained-bomb-cyclone-bombogenesis-winter-weather-viral-videos-spd/ 1 Link to comment Share on other sites More sharing options...
IBob Posted December 11, 2019 Share Posted December 11, 2019 Reminds me of camping on a freezing night in the Scottish Highlands. When we woke in the morning there were these little brown things bouncing around inside the tent. I've no idea what they were, but as the sun came up and they thawed, the smell was terrible..............( 2 Link to comment Share on other sites More sharing options...

planedriver Posted January 16, 2020 Share Posted January 16, 2020 I once went to see this lady for a psychic reading, and as I walked in she said "hello, whats your name". I replied, "sorry, I must be in the wrong place". 1 Link to comment Share on other sites More sharing options...
