Why does a fart smell less the longer it has been around in the air? Explain, using the particle model.
Gas particles spread out in whatever space/room they are in, so eventually they get so far apart that they are just mixed in with the air and are not concentrated enough to smell.

Since the bonds between particles are stronger in solids than liquids, most substances are denser in solid form than they are in liquid form.
For example, solid gold will sink if you drop it into liquid (melted) gold.
What is one very common substance which breaks this rule?
Water--ice (solid water) is actually less dense than liquid water, so it floats on top of it!
