  • Understand the relationship between the arrangement of particles of matter and bond strength.

Everything You'll Have Covered

How does the strength of the bonds between particles in a solid compare to the strength of the bonds between particles in a liquid?

~ The strength of the bonds between particles in a solid is stronger than the strength of the bonds between particles in a liquid. Liquids have more space between particles, so the force between particles is weaker, which makes the bonds between particles weaker.

Which state of matter has the weakest bonds between its particles?

~ Matter in the gas state has the weakest bonds between particles, because a lot of space exists between each particle. Liquids have stronger bonds than gases, and solids have stronger bonds than liquids.

Explain what occurs when heat is added to melt a solid into a liquid.

~ When heat is added to melt a solid into a liquid, it causes the bonds between the particles in the solid to weaken and break. As the bonds break, the particles move apart and the matter undergoes a change from solid form to liquid form.

What are two effects of condensation and freezing?

~ During condensation, when matter changes from a gas state to a liquid state, and freezing, when matter changes from a liquid state to a solid state, the bonds between particles get stronger. In addition, energy in the form of heat is lost during both processes.
