adsl1981 Posted December 7, 2005 Share Posted December 7, 2005 Hello, This may seem like a bit of a silly question but out of interest is there anyway of keeping a liquid that is already very cold eg. liquid nitrogen and keeping it cold using electricity ! i know it seems silly but any ideas Thank you Link to comment Share on other sites More sharing options...
xeluc Posted December 7, 2005 Share Posted December 7, 2005 The only two methods of keeping liquid nitrogen liquid (that I know of) are keeping it compressed and cooling it. I know there are ways of cooling things way below the boiling point of nitrogen (Using lasors for creating bose-einstine condensates for example) but I don't know of any.. "Consumer-friendly" ways of getting temperatures as low as the boiling point of nitrogen, except of course, setting out liquid nitrogen... Link to comment Share on other sites More sharing options...
