Example Questions

Example Question #41 : Phases Of Matter

Distillation requires which of the following?

Possible Answers:

Vaporization only

Condensation only

Vaporization and condensation

Neither vaporization nor condensation

Either vaporization or condensation

Correct answer:

Vaporization and condensation

Explanation:

Distillation is the process by which liquids are purified of impurities. Distillation first requires vaporization of liquids to become pure gases. The gases are then cooled and turned back into pure liquids via condensation into a separate container. A good distillation will remove all impurities from the liquid. This is why distilled water is used for chemical solutions; it does not contain ions or other impurities that could interfere with reaction.

Example Question #51 : Phases Of Matter

Which of the following occurs during vaporization?

Possible Answers:

Atoms become spaced further away from each other

Atoms become highly organized in patterns

Atoms disappear and are destroyed

Atoms get closer together and form a more rigid shape

Correct answer:

Atoms become spaced further away from each other

Explanation:

Vaporization refers to the phase change from liquid to gas, also known as evaporation. When becoming a gas, atoms spread out and expand to fill whatever container they are in. Conservation of mass hold that atoms are never created nor destroyed. Atoms becoming more organized and forming a more rigid shape describes a phase change toward becoming solid.
