Kind of a weird tangent but can anyone elaborate on this quote: "trap a drop of water between two other liquids and heat it, you can raise the temperature to at least 300 °C with nothing happening"
I knew you could change boiling point with pressure but is this suggesting that doing something like having a layer of oil on top of an ambient pressure pot of water would prevent boiling? I tried googling for some elaboration but only found discussions of superheating water via pressure changes.
- garof 5y agoI'm not sure of the experiment that this might be referring to, but it sounds like superheating[0]. Trapping the drop of water between two other liquids could be some version of a "clean container, free of nucleation sites" as described in the first paragraph of the wikipedia article. Other ideas?
