Is hot water less dense than cold
WebAnswer (1 of 11): The "counter argument" you link to cites E = mc^2 and the higher energy content of hot water. First off, note the "c^2" in that formula. That's the speed of light, … WebBecause there's more space between the molecules, a volume of hot water has fewer molecules in it and weighs a little bit less than the same volume of cold water. So hot …
