This week, my class has been studying water; its molecules and their properties. Water isn't a tear drop shape like everyone thinks. It's actually like a blob. I always thought that it was tear but its not. In the morning, dew on leaves are a spherical shape because the shape increases the density of the water drops. Also, if you try and put as much water as you can on a penny, it kind of has a bent shape on the top. Thats because of the surface tension. Also, while holding a long, wet string vertically, we found out that the water kind of attached to each other. The water had a swirl to it while it when down the string. How it got that way, I'm not for sure, but I know I will find out.
It takes more energy to turn a solid to a liquid, then it is to take a liquid to a gas. Water molecules are cohesive and adhesive. Cohesive is when water flows freely, but the water molecules don't separate from each other. Adhesive is the opposite.
Water is a very funny element that we have on our Earth, and I want to learn more about it.
