Question

which statements describe phase changes? check all that apply. particles in a liquid need to move more slowly in order to freeze. attractive forces overcome the motion of particles when a solid sublimes. attractive forces between the particles in a liquid are broken when a liquid boils. particles in gas move fast enough to make more attractive forces when the gas condenses.

Explanation:

• Freezing is a phase - change where liquid turns to solid. Slower - moving particles in a liquid allow for the formation of a solid structure.
• Sublimation is when a solid directly turns to a gas. In this case, the attractive forces are overcome by the motion of particles, not the other way around as stated.
• Boiling is when a liquid turns to a gas. The attractive forces between liquid particles are broken during this phase - change.
• Condensation is when a gas turns to a liquid. Particles in a gas slow down and attractive forces become more significant, not that they move fast enough to make more attractive forces.

Answer:

Particles in a liquid need to move more slowly in order to freeze.
Attractive forces between the particles in a liquid are broken when a liquid boils.
