Compared to the particles of a gas, the particles of a liquid
are not in constant motion
collide with the sides of the container, but not with each other
do not completely fill their container
can move longer distances
have more space in between the molecules
Do you have a question?
The only differece between molecules in a liquid and molecules in a gas, is that molecules in liquid are more densely packed, have more frequent collisions, and have much higher cohesive attraction.
both liquid and gas are in constant motion.
gas melecules travel longer distances.
gas molecules have more space between molecules.
This leaves "do not completly fill their container" I have no idea what this means. Atoms are mostly empty space anyway, whether the molecules are gaseous or liquid. So knowing the other three are wrong, your teacher must have something in mind here, I know not what...so choose this one, even if it is nuts.
