MARS 1010- Objectives Properties of Water Reading Assignment: Chapter 5 in Sverdrup and Armbrust 1. What are the two types of chemical bonds associated with water? Which type has the most influence over the properties of water? Why? Covalent bonds connect Oxygen to two Hydrogen atoms. It is a very strong bond Hydrogen bonds connect water molecules to other water molecules. They are much weaker than covalent bonds (4% the strength). o Cohesion- process in which hydrogen bonds hold water molecules together. o Solid has all hydrogen bonds o Liquid has some hydrogen bonds o Gas has no hydrogen bonds. 2. What is “latent heat?” Which is greater, latent heat of vaporization or latent heat of fusion? Why is there a difference? What are the important oceanic consequences of water’s high latent heat? Latent heat is also know as “hidden heat” and is the amount of energy it takes to move from one state of matter to another. o This is why it takes a long period of time of cold weather to freeze water. Latent heat of fusion is the heat necessary to change the state of water between a solid and a liquid Latent heat of vaporization is the heat necessary to change the state of water between a liquid and gas. Latent heat of fusion is greater than latent heat of vaporization 3. What is “heat capacity?” Why is it important to the ocean system? Heat capacity is the amount of heat
