### Activity Six: States of Matter and Intermolecular Forces

1. Convert 0°F, 32°F, 70°F, and 212°F to Kelvin0°F -- 255.37 K
32°F --  273.15 K
70°F --294.26 K
212°F -- 373.15 K

2. Complete the Teaching Idea: States of Matter Simulation Lab by Kelly Vaughan. Complete the lab worksheet as if you were a student, and then post this on your blog.

3. In the States of Matter simulation, choose the Solid, Liquid, and Gas Tab at the top of the screen. Choose the water molecule and cool the water to 0 K. Describe how the water molecules are aligned and attracted to each other. Which atoms are attracted to which other atoms?

The water molecules are aligned with the hydrogen atoms touching the oxygen atoms. The water molecules aren't moving at all and are in one big cluster.

4. Temperature & Pressure at which oxygen becomes liquid?
1. 73K & 0.04 ATM
2. 55K & 0.03 ATM
3. 58K & 0.20 ATM

5. List and describe at least two Science Standards that this activity addresses.

B.4.1 Use encyclopedias, source books, texts, computers, teachers, parents, other adults, journals, popular press, and various other sources, to help answer science-related questions and plan investigations
We used a computer simulation to complete a worksheet about states of matter, so we could learn what happens when you cool or heat up certain molecules.

E.4.2 Show that earth materials have different physical and chemical properties, including the properties of soils found in Wisconsin
We used the simulation to explore how different molecules look in their three different physical states: solid, liquid, and gas.
