The particles are too far apart to have a fixed volume.

The forces between particles are strong enough to keep them together but not strong enough to keep them in one place.

The particles move too fast to be held together at all.

Gravity only affects liquids, not solids or gases.

Gas particles have less energy than solid particles.

Gas particles are moving much faster than solid particles vibrate.

Solid particles are much larger than gas particles.

Gas particles are more strongly attracted to each other.

The temperature at which water freezes.

The temperature at which all particle motion theoretically stops.

The temperature at which all gases become liquids.

The temperature at which particles have the most kinetic energy.

The different types of particles will eventually react and disappear.

The particles of the two gases will eventually separate into two layers based on density.

The particles of both gases are in constant, random motion and will remain mixed.

The heavier gas particles will stop moving while the lighter ones continue.

Gain potential energy and lose kinetic energy.

Lose potential energy and lose kinetic energy.

Gain both potential and kinetic energy.

Lose potential energy and gain kinetic energy.

Pressure decreases because particles move slower.

Pressure increases because the particles collide with the walls more often and with more force.

Pressure stays the same because the volume is constant.

Pressure decreases because the particles become smaller.
