Question

Choose the statement that best completes the sentence.

Whether a substance is a gas, liquid, or solid is dependent on the natural attractive forces between molecules and


how the molecules collide with the container.
the collisions between the molecules.
the kinetic energy of the molecules
the extent of molecular motion as determined by the average KE and temperature.
none of the above

Answer 1

the collisions of the molecules

Answer 2

Answer: Option (b) is the correct answer.

Step-by-step explanation:

In solids, the force of attraction are strong therefore, there will be no collision between the particles.

In liquids, there will be less force of attraction between the molecules therefore, there will be collisions between the molecules.

In gases, as there is no force of attraction between the molecules therefore, there will be more collisions.

Thus, we can conclude that whether a substance is a gas, liquid, or solid is dependent on the natural attractive forces between molecules and the collisions between the molecules.
