The 7DC Particle Model of Matter

We made a particle model of matter using members of 7DC as particles. This was for the Particles module in year 7, but we have adapted it for year 8 heating and cooling.

Keywords:
Solid, Liquid, Gas, Melting, Evaporation, Boiling, Freezing, condensation, sublimation

@TheMolliej99

hi i think that I know you did your teacher tell you to watch this for a school assignment?

I'm probrably in your class

[TheMolliej99]

nice nice

@gespilk Nitrogen can be a solid between negative 210 Celsius and its boiling point, -252 Celsius. Molecules move faster when heated because (theoretically) hotter objects have more kinetic energy and the kinetic theory of matter says that all particles are in constant motion and move faster when spread out by being heated.

and I don't know the other two, sorry.

[gespilk]

Is there a substance that can never be solid? Nitrogen perhaps?

How come molecules move faster when heated instead of getting cooked?

Why would heat make a molecule "move" instead of just make it "expand" or "fall apart" to individual atoms or just "pass through" the molecule?

What they( scientists) mean by "heat" when they say the Universe was so "hot" that no atom could exist?

excellent!

@imtheboss48 who are you talking you probably watched this is science class

[karingklein]

Our 6th grade science class liked your video very much. However, we noticed a few inaccuracies in your video:1)Sublimation is the phase change from solid to gas. Deposition is the phase change from gas to solid. 2)The "molecules" did not travel in straight lines until they collided with something. 3)All molecules in a pure substance are exactly the same, but not all the molecules in the model looked the same (hoods were off of some). THANKS!!

Used by a professor of mine to teach. Gets the point across well!

That was soo cute!!!!

wow, awesome way to explain the states of matter. LOVE IT
