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 the water was cooled the molecules were slower. Hydrogen molecules held them together. The oxygen molecules are very attracted to one another as well.
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.Temp: 589K
Pressure: 62ATM
List and describe at least two Science Standards that this activity addresses.D.4.3. Understand that substances can exist in different states-solid, liquid, gas.
This activity clearly shows in effective pictures how solids, liquids, and gasses differ in shapes and consistencies. The pictures are very clear and the simulation is very easy to follow.
D.8.2. Use the major ideas of atomic theory and molecular theory to describe physical and chemical interactions among substances, including solids, liquids, and gases.
This activity, paired with other knowledge students should have learned up until this point, will aid in the learning of how different solids, liquids, and gases compare to major themes they have learned in their science career.
