Investigation:

3. Predict what the molecules of a solid, liquid and gas look like. Illustrate your prediction with a drawing.

Solid Liquid Gas

4. Predict how a change in temperature (heat or cold) will effect each phase change. Write or draw prediction.

Solid Liquid Gas

Heat Cold Heat Cold Heat Cold



5. Complete the table below by exploring the “Solid, Liquid, Gas” tab in the simulation. Before going to next element click reset. Test your predictions and record your observations by recording the temperature and illustrations of each substance in the three states of matter.

6. Now, while still on water, use the slider on the bottom of the program to Add Heat. Notice the thermometer at the top of the program. What temperature scale is this thermometer showing? _____

7. What happens to the water as you increase the temperature?



8. Can you determine the melting/freezing of water in Kelvin and in Celsius? _________________________

Click on -273(C. What is it the temperature for? ___________________________________________

What is standard room temperature in (C? ________________________________________________



-Watch until all water is gone. Be sure to watch the entire animation above. Then watch the animation again and pause as needed.

9. Describe what happens to temperature and the motion of the particles in a block of ice as it melts and boils.

a. Describe the temperature before melting begins-

b. Describe the motion of particles before it begins to melt –

c. Describe the motion of particles during melting –

d. Describe the temperature during melting-

e. Describe the motion of particles as it heats to boiling –

f. Describe the motion of particles when it is boiling –

g. Describe the temperature during boiling-

h. Describe the motion of particles as it heats after boiling -

i. Describe the temperature after boiling-



–Watch until all water is gone. Be sure to watch the entire animation above. Pause as needed.

10. In the above simulation, describe the temperature (increasing, decreasing or staying the same) as the solid heats, as it melts, as a liquid, and as it boils.

a. Describe the temperature as the solid heats-

b. Describe the temperature as the solid melts –

c. When does the change in solid phase to liquid phase occur?

d. Describe the temperature as the liquid heats–

e. Describe the temperature as the liquid boils –

f. When does the change in liquid phase to gas phase occur?
