intermolecular+forces

** Procedure:  ** Open the internet browser and enter the address: [|http://phet.colorado.edu] Click on “Play with Sims” and select “Chemistry” from the menu on the left. Open the “States of Matter” Simulation and select “Run Now” ** Learning Goal: ** By the end of this activity I want you to be able to demonstrate knowledge of the states of matter by explaining: · How the molecules in a solid, liquid and gas compare to each other. · How temperature relates to the kinetic energy of molecules. · How attractive forces between particles will determine the phase of matter at certain temperatures

What happens to the particles as you increase the heat?  3. Compare water as a solid (ice) to other solid compounds. What is different about the water? Read “Water: Some Unusual properties” found on page 469. Summarize the six consequences of this type of behavior of water.
