I know this is a dumb question. Can someone tell me why water has a molar vaporization of 40.66...

...kj/mol? Is there some sort of way to derive from that value? or:...kj/mol? Is there some sort of way to derive from that value?or:When you observe

...kj/mol? Is there some sort of way to derive from that value?

or:...kj/mol? Is there some sort of way to derive from that value?

or:When you observe something, that is science. When you ask why, that is religion. Because of steam trains, water has been very carefully studied for hundreds of years. And now at last they have found a way to calculate the boiling point from first principles. I have no idea where you would look to find that information.
