demo solid gas liquid
1. What atom did you chose?
Step 2 – Select a starting state, observe the atoms in the simulation for a minimum of 10 seconds. Below, write a sentence or two about what you observed for each state.
2. Solid
3. Liquid
4. Gas
PHYS 110 – 1077 Demo – States of matter 4/9/2020
Step 3 – Click solid for your state. Absolute zero occurs at -273°C. The simulation will not go lower than -271°C. Reduce the temperature to -271°C.
5. What do you notice about the motion of the atoms at -271°C compared to when you click solid?
Step 4 – Click gas for your state. Increase the temperature by a minimum of 100°C. The simulation does not seem to have a maximum temperature.
- What is your new temperature?
- What do you notice about the motion of the atoms at your new temperature compared to when you clicked gas?
Step 5- Choose a phase change (solid to liquid, or liquid to gas). Increase or decrease the temperature from the starting temperature to the value in the table above.
- What phase change are you looking at? What state did you start in?
- What do you notice about the atom motion? Is it more similar to the starting state or the new one? Include a screen shot of your system.
- Allow the simulation to run for 1 minute, do you notice a change in motion? If so, what changed?
Step 6 – Increase or decrease the temperature by 1°C, in the direction you already began moving in Step 3.
11. What do you notice about the motion now? What has changed? What has stayed the same? Again, include a screenshot of your system.
