Activity Six: States of Matter and Intermolecular Forces

1. Convert 0°F, 32°F, 70°F, and 212°F to Kelvin

Fahrenheit	Kelvin
0 degrees	255.37 degrees
32 degrees	273.15 degrees
70 degrees	294.26 degrees
212 degrees	373.15 degrees

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?

Instead of being in a neat order, tightly packed together, water had a lot of space in between the molecules. The molecules did not move around freely. Even when a solid, there was still space in between the molecules. The oxygen atoms were attracted to the hydrogen atoms.

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.

Oxygen became a liquid at 65 K, and ATM was generally at .25

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

D.4.3. Understand that substances can exist in different states-solid, liquid, gas

C.4.6 Communicate the results of their investigations in ways their audiences will understand by using charts, graphs, drawings, written descriptions, and various other means, to display their answers.
