Activty 6: States of Matter and Intermolecular Forces

1. Convert 0°F, 32°F, 70°F, and 212°F to Kelvin
0°F- 255.372
32°F- 273.15
70°F-294.261
212°F-373.15

2. States of Matter Simulation Lab by Kelly Vaughan:

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?

When I cooled the water to 0 K the molecules slowed down to barely moving at all.  They were all strung together by the hydrogen molecules touching each other.  (red molecule to red molecule)

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.

Temperature: 589 K

Pressure: 62-63 ATM

5. List and describe 2 standards that this activity addresses.

D.4.3. Understand that substances can exist in different states-solid, liquid, gas
       -Through the simulations I observed and the changes that are made when water becomes  liquid, solid or gas.

D.4.4 Observe and describe changes in form, temperature, color, speed, and direction of objects and construct explanations for the changes
      - This simulation made it posible to change the temperature of the molecules and then observe the speed that they were traveling and the form they were in.
