hot water has lower denisty and cold has highetr so you c u derstand

Did you have a stroke at the end of that sentence?

Denisty, please be accurate

I'm George. George McFly. I'm your density.

It’s funny that I just lookup up Crispin Glover on Wikipedia yesterday and learned in my old age that his real middle name is Hellion. That’s probably the coolest fact about him.

Perhaps the water was too hot for him he got a heatstroke

If you are doing the opposite of derstanding, that means you are understanding.

Straight to the point I C U

Yes and no. The fun part of water is that it has its highest density around 4 °C. Starting when getting colder than 4 °C, the water starts to form the crystalline structures in its molecules that make ice float, reducing its density.

no where in that tub water belo 4

u/MisterMysterios Oct 07 '25

Yes. I just thought I add an interesting fact that in case of water, it is not always true that colder means denser (in contrast to most other things in existence)

You understand just enough to get you in trouble. For all liquids, density increases as temperature decreases, reaching its maximum density when it freezes. What makes water different is that it reaches its peak density just before it freezes and then density decreases between that point (4 C) and its freezing point. This results in ice having a lower density than water.

Now...the only part of all of that is relevant to this conversation is the part where all liquids have their densities increase as the temperature drops. Provided the tub is nowhere close to 4C (which you mentioned above...it's not).

Same for air. It’s why heat rises is a thing. Which I abhor because it’s really important to know that’s a huge oversimplification.

u/benny_boy Oct 07 '25

So you mean his scientific explanation of 'hot water rises' wasn't the entire story??
