Watch the KEx and KEy values as they change with each collision, representing the total x and y kinetic energies of the particles. **Both KE energies increase and then lower back down.
Watch the 'red' particle for a couple of minutes, estimating the average time between its collisions and its average speed (one of the speeds given near the top of the screen corresponds to that of the 'red' particle--which is it?).
The first speed under ""speeds of two molecules"" is the 'red' particle because it is moving at a much faster rate generally than the 'blue' particle. I'm having trouble estimating the time between collisions but its average speed is about 4.
Watch the 'blue' particle, and speculate on what property of this particle is different from that of the other particles.
**When the 'blue' particle crosses paths or bumps into the 'red' particle it generally speeds up.
Watch as the 'red' particle sometimes turns yellow. What causes this?
**The 'red' particle never turned yellow. It should be due to a phase change.
What property does the particle have when it is yellow?
What might the graphs represented at the right of the screen represent?
**The graphs represent how the KE changes over time."
&#Good responses. Let me know if you have questions. &#
