My chemistry teacher said that he could boil water using ice without applying any heat to the water. He said he won a bet from his friends regarding this. However, he hasn't shown us or told us how he did it. He only told us that he used to ice to equalize the atmospheric pressure and the internal pressure of the flask he used to hold the water. I don't why he would make something like this up. So, I'm curious
, how did he do it?
