Particle movement and temperature

As we heat a substance, we see an increase in the speed of the particles as well as an increase in the space between particles. As we cool a substance, we see a decrease in the speed of the particles, as well as a decrease in the space between particles.

It is a very good video explaining the concept brilliantly.

Now I understand why pressure goes up when heating any gas

Anyone else just watching this for school? ._. Or is it just me????

Anyone else studying this for school?? Hello???

Why do they get more energy when they are in contact of heat.? As compared to coolness

[teacherconor]

at fixed volume, increasing temp does NOT increase space between particles

[temika]

Haha, yes. This is very entertaining. I do have a question, however. What balls are you using and can I have exactly four of them?

That's not the correct diagram for a liquid

Who's here from middle school? B)

This is not correct and reinforces a very common misconception that students have. You show a very high pressure gas - not a liquid. Particles should remain in contact in a liquid.
