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:

Phase - changes involve alterations in the state of matter due to changes in temperature and/or pressure. When a liquid boils, the particles gain enough energy to overcome the attractive forces between them. When a gas condenses, the particles slow down and attractive forces become significant. When a solid sublimes, particles directly change from solid - to - gas phase, implying they overcome the forces holding them in place. Particles in a liquid do not need to move more slowly to freeze; rather, they lose energy and arrange themselves in a more ordered pattern.

Answer:

Particles in gas move fast enough to make more attractive forces when the gas condenses.
Attractive forces between the particles in a liquid are broken when a liquid boils.
Attractive forces overcome the motion of particles when a solid sublimes.
