Activity #6

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

0 F=2.55.2 Kelvin
32 F=273 Kelvin
70 F=294.1 Kelvin
212 F=373 Kelvin

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?
A. The molecules started to slow down to the point where they were barely moving. The hydrogen molecules were attracted to each other and came close together and were touching.

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-589 K, Pressure- 63 ATM

5. List and describe at least two Science Standards that this activity addresses.
A.4.2 When faced with a science-related problem, decide what evidence, models, or explanations previously studied can be used to better understand what is happening now
-We did this by looking at all sorts of modelling and trying to use the models to better understand what was happening.
A.4.3 When investigating a science-related problem, decide what data can be collected to determine the most useful explanations
-We collected alot of data throughout this activity by looking at all sort s of different models, draw, and explain what was taking place in the photos.
