Activity 6: 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? 


They are aligned very closely and in an arranged order. They do not move freely like they did in the liquid and gaseous states.  The hydrogen molecules are attracted to the oxygen molecules.

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 becomes a liquid at 71K and  .35 ATM

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

C.4.2 Use the science content being learned to ask questions, plan investigations, make observations, make predictions, and offer explanations.


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.
