Hi everyone -
Here's one of those questions that is so basic, yet I, at least, can't
answer it.
For water to turn to steam it must absorb 540 calories/gram. This is heat of
vaporization. But what's going on with the water molecules. Why does it need
to absorb this heat to vaporize? Are the water molecules adhering - and the
energy breaks these bonds? What's really going on?
(Ditto question for the phase transition from ice to water)
Thanks for the help,
Steve Miller
