Question

What keeps the particles of a liquid from spreading out to fill an entire container in the same way that gas particles do?

a. they move too quickly to be separated from one another.

b. the forces of attraction among them limit their motion.

c. they are covalently bonded to one another.

Answer 1

b. the forces of attraction among them limit their motion.

Answer 2

b. the forces of attraction among them limit their motion.

Step-by-step explanation:

In solids, the particles are tightly packed. The solid has fixed shape and volume.There is strong inter-particle force of attraction which prevents the motion of particles in solids. Thus, the particles in solids can vibrate about their fixed position. Liquids have fixed volume but not shape. Gases don't have fixed shape and volume. The particles of liquid do not spread out like gases. This is because of the inter particle attraction which prevents them from moving far away. In gases, the inter-particle distance is large and thus, particles have weak force of attraction.
