Under the same conditions of temperature and pressure, a liquid differs from a gas because the particles of the liquid:
A. have no regular arrangement.
B. are in constant straight-line motion.
C. take the shape of the container they occupy.
D. have stronger forces of attraction between them.
E. have weaker forces of attraction between them.
Liquids and gases take the shape of the container they occupy and both have no regular arrangement (remember solids have a regular arrangement). Both liquids and gases have particles that are in constant straight-line motion. But liquids have a constant volume because the forces of attraction between the particles keep them together. Gases do not have a constant volume and the forces of attraction between particles are weaker.
