[6P22] Day 1

A container holds a small amount of water. Which action would cause the molecules of water to move more slowly?

• Cooling the water.

• Heating the water.

• Stirring the water.

• Swirling the water.

Which of the following correctly pairs a phase of matter with its description?

• Solid: Particles have no motion.

• Liquid: Particles expand to fill any container in which they are placed.

• Gas: Particles have higher amounts of energy than when in the liquid phsae.

• Liquid: Particles are more strongly attached to one another than when in the solid phase.

What change occurs when a liquid evaporates?

• The particles absorb heat and get close together.

• The particles absorb heat and spread farther apart.

• The particles release heat and get closer together.

• The particles release heat and spread farther apart.

In which way are evaporation and condensation similar?

• Both cause decreases in air temperature.

• Both cause increases in air temperature.

• Both are causes by the warming of the atmopshere.

• Both are caused by changes in heat energy.

What happens to water molecules during the boiling process?

• They move faster and move farther apart as they absorb heat.

• They move faster and remain close together as they absorb heat.

• They move more slowly but move farther apart as they lose heat.

• They move faster and move farther apart as they lose heat.
