Let’s take a look at a molecule of matter we are all familiar with-WATER!
Let’s take a look at a molecule of matter we are all familiar with-WATER!
Water is 2 hydrogen molecules and 1 oxygen molecule!
We are going to look at water molecules as they travel through the water cycle and the 3 states of matter.

The Water Cycle
All the water on Earth is recycled through the water cycle as it travels through different states of matter.

You place the ice cube into your sugary hot cider and it melts into water and dissolves into the cider.

Dissolving means the matter is incorporated into the matter of the original solution (often solid to liquid).
