Convert 0°F, 32°F, 70°F,and 212°F to Kelvin
0= 255.372 K
32=273.15 K
70=294.261 K
212= 373.15 K
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.
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
0K. Describe how the water molecules are
aligned and attracted to each other.
Which atoms are attracted to which other atoms?
The water molecules are all aligned together and are attracted to each
other.
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 would make oxygen a liquid would be 119 K and the
pressure about 3 ATM.
List and describe at least two Science Standards that this activity
addresses.
D 4.2 Group and or classify objects and substances based on their
properties.
D.4.3 Understand that substances can exist in different states-solid,
liquid, gas
