Activity #5

States of Matter and Intermolecular Forces

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

0F = 255.372K
32F = 273.15K
70F = 294.261K
212F =  373.15K

2. Complete the Teaching Ideas "States of Matter Simulation Lab" by Kelly Vaughn:

 3.  In the states of matter simulation, chose the solid, liquid, and gas tab at the top of the screen.  Choose the water molecule and cool the water to 0K.  Describe how the water molecules are aligned and attracted to each other.  Which atoms are attracted to which other atoms? 

The water molecules remain very close together and the atoms that are attracted to other atoms are the hydrogen and oxygen atoms. 

4. Record a  possible temperature and pressure required to make oxygen a liquid:

 

A possible temperature that could be required to make oxygen a liquid is:  114K

A possible pressure that could be required to make oxygen a liquid is: 4ATM

 

5. List and describe at least 2 science standards that this activity addresses:

D.4.3. Understand that substances can exist in different states-solid, liquid, gas
* We could see through the simulation that substances exist in 3 different states and how they react in certain circumstances. 

D.4.4 Observe and describe changes in form, temperature, color, speed, and direction of objects and construct explanations for the changes.  * We watched the molecules change due to temperature and the speed of them would change based off the temperature and form as well.
