I'm going to take this hot teal water and put it in this cold water. And then I'm going to poke a hole in the roof and see what happens. Hopefully it's hot enough. It's going to flow out.
Is it going to flow out and rise or is it going to flow out and sink? It's going to rise. Higher. Yeah, Chuck.
Where is all the green color going? Upstairs. It's rising up, right?
So on your paper, draw your macro picture. We've got the tub of cold water. We have our vial.
With colored water, so color it in. And draw the colored water coming up. And we're going to label that hot water. So is hot water more dense or less dense than cold water? Less.
Less dense, because it's hot, right? So if we draw our particle picture of our hot water and our cold water. Did I add a substance to it this time?
No. So if we start with our fresh water, we're going to make it the same as we did before. So this is, that's not nice, but cold. Cold, fresh, just like before, water. How do I want to manipulate the particle picture to show a change?
If you're heating it up, what are you doing to the molecules? Expanding them. So I'm going to draw the same four, taking up more space. So the hot water is less dense because the particles expanded due to the heat.
So it floats. The end.
