Activity 6: States of Matter and Intermolecular Forces

1. Convert 0°F, 32°F, 70°F, and 212°F to Kelvin
0°F = 225k
32°F  = 273.15k
212°F = 373.15k

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. You can scan it or just take a picture of it.

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 atoms are not moving at all, they are still staying together though because of their molecular forces. The white atoms are attracted to the red ones. As you can see in the picture above the atoms are not in a very neat form but if you are looking at how they are connected you can see that the white molecules are being held to the red ones.

4. Switch to the Phase Changes Tab on the States of Matter simulation. Notice how on the bottom right there is a small red dot that indicates where the system is at as far as temperature, pressure and state of matter. Play with the simulation to notice changes, notice that when you push down the pressure can go way up and explode the box. On your blog, report a temperature and pressure required to make oxygen a liquid. This is sometimes how the oxygen exists in pressurized oxygen tanks, perhaps like ones you may use to go diving.
A temperature and pressure that makes Oxygen a liquid would be 99K and 0 for a pressure.

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

A.4.3 When investigating a science-related problem, decide what data can be collected to determine the most useful explanations. This standard apply's because in order to answer the questions for this assignment and be able to understand  the states of matter you need to be able to understand what happens when the temperature of something in order to understand how something can change between the states of matter.

C.4.5 Use data they have collected to develop explanations and answer questions generated by investigations. This standard apply's to this assignment because we are adding heat or cooling the substances down to get a desired effect. We are then using this data to decide if something is in a particular state of matter and how it would look.
