Phase Change Quiz

What happens when my glass of water is sitting in the sun and disappears into a gas?

• evaporation
• burning
• melting
• freezing

In a solid, the particles

• vibrate in place
• slide past one another
• overcome the strong attraction
• move freely in any direction

Condensation is . . . .

• gas to liquid
• liquid to gas
• gas to solid
• solid to liquid

Freezing (or solidification) is . . . .

• liquid to solid
• solid to liquid
• solid to gas
• solid to plasma

5. What is it called when a solid turns directly into a gas?

• Sublimation
• Condensation
• Liquid

Endothermic phase changes include

• conduction, convection and radiation
• freezing and condensation
• vaporization and condensation
• melting, boiling, evaporation and sublimation

Exothermic phase changes include

• conduction, convection and radiation
• freezing and condensation
• vaporization and condensation
• melting, boiling, evaporation and sublimation

________________________ is the temperature at which a solid begins to liquefy.

• boiling point
• condensation point
• melting point
• evaporation point

At higher temperatures

• particles in an object have less energy
• particles in an object move faster
• a gas contracts

Both boiling and evaporation are forms of vaporization. What is the difference between them?

• Boiling liquids have intense heat added to it, evaporating liquids take heat from their environment.

• Boiling happens quickly, evaporation happens slowly.

• Evaporation occurs only at a liquid's surface, boiling occurs throughout the liquid

• All of these reasons
