Some time back, I had a bad habit. I would open a cupboard to get something, then forget to close it. My wife was somewhat miffed by this – understandably, because our kitchen had an infestation of moths at the time. So, she found herself having to tell me, again and again – close the cupboard doors!
This post is wrong!! It’s been pointed out that adding salt to boiling water raises the boiling point. It doesn’t lower it. So something very strange was happening in the experiment below. Perhaps it was just a screwy thermometer??
Just for a change, here’s a post about Chemistry. Or Physics, some might argue. I say Chemistry.
My son had just finished some questions in a science workbook, and I had to mark it. Unfortunately, there was one question I didn’t know the answer to – does adding salt to water lower its boiling point?
