Name______________ Block_____ Study Guide: Water and its Properties (Test will be similar) 1. Draw the solar system (Bohr) model of the H2O molecule. (a) Show the number of protons and neutrons of each element at the center of each atom. (b) Show where all electrons are in their orbits. (c)Show any areas of positive or negative charges. o 2. In the area below, using drawings of the H2O molecule about this large: show motion, both in direction and amount show how 12 molecules of H2O will be arranged when the H2O is (a) A gas (6 molecules only are needed) (b) Liquid (c) A solid 3. Explain why the H2O molecule is called a “polar molecule”: o O and to 4. Define the following, and provide an example Capillary action of water example Surface tension of water example Immiscibility of water example Water as a solvent example 5. Three factors that are special to water affected the “drops on a penny” acitivity. What are the 3 factors, and how did they let students build up a large mound of water on the penny? 6.. Fill in the blanks below for the states of matter of H2O and its transition verb. Starting state Transition Word Ending State A. ___solid(ice)_ ___________ ____________ B. ___________ ___________ ____________ C. ___________ ___________ ____________ D. ___________ ___________ ____________ E. ___________ ___________ ____________ F. ___________ __________ ____________ 7. Water has a very high specific heat”: Explain what that sentence means, and apply it to weather AND climate on Earth. 8. Imagine that a rogue H2O molecule was part of a gang in South Carolina that destroyed homes, farms, offices, and stores while also causing the deaths of wild animals, farm animals, pets, and people. Using a separate sheet of paper, prepare a poster warning people about the dangers of this molecule when in an unruly gang.
