Properties of water notes:
- Water is made up of oxygen and hydrogen
- Hydrogen bonding- the weak attraction between the weakly positive hydrogen atoms and the weakly negative oxygen atoms of a different molecule.
- When water molecules attract different water molecules it's called Cohesion.
- The attraction of water molecules to themselves creates a "film" on the surface called Surface tension.
- Water that attracts other materials is called Adhesion.
- High heat of evaporation is broken hydrogen bonds
- High latent heat of fusion releases heat when water freezes
- Density= Mass/Volume
- The closer the atoms, the more dense it can be
- Solid forms have little amount of density in it.
- Cold things have less dense, heat however has more.
- Atoms are the smallest units of matter that retains it's properties.
- Atoms are usually neutrally charged because of the number of protons, electrons, and neutrons.
- Unevenly charged atoms are called ions
- Water is a polar molecule
What I learned:
What I learned in this note taking process is that there are many forms of water molecules, and what the can do. Adhesion is when the water molecules attract other types of material. Cohesion is when the different water molecules attract each other. And so much more! without any of these molecules our world would be a dried up dessert. If it weren't for capillary action, our trees would be dead and we would have no plants, fruits, vegetables, paper, and air. These things are important because it helps us get our nutrition from foods, paper to learn, trees to breath, and many other things we need in our lives.
