1. A polar molecule is like a magnet: the two ends are different and if you try to put two like ends together, they will repel. But, if you put two opposites together they will attract.
2. Water is capeable of dissolving many substances which is why it is a good solvent. Its known as a universal solvent because it dissolves the most of any liquid.
3. A buffer resists or tries to stop pH change to help maintain homeostasis.
4. Soda is usually considered a solution because it contains sugar, additives, and other sweetners dissolved.
5. Surface Tension (I think) because the water is so attracted to eachother that i can be hard to break the surface of water. Water drops, when water drips it does not break into individual water molecules due to cohesion (due to hydrogen bonds), and stays on the items its dripping down due to adhesion.
6. In colder temperatures, water freezes into ice which is less dense then water, causing it to float. This helps so all the water underneath doesnt freeze, allowing aquatic life to still live.
Hope this helps!
