Which best explains why the outside of a cold drink gets wet on a muggy August day? The gaseous H2O in the air:

• gains energy from the atmosphere, vaporizes, and shows up as liquid water droplets on the outside of the glass.

• loses energy from the atmosphere, vaporizes, and shows up as liquid water droplets on the outside of the glass.

• loses energy due to contact with the cold surface, condenses, and shows up as liquid water droplets on the outside of the glass.

• loses energy due to contact with the cold surface, undergoes deposition, and shows up as liquid water droplets on the outside of the glass.

Which of the following expresses a key similarity between boiling and evaporation?

• Both are processes of sublimation when a solid becomes a gas.

• Both are processes of vaporization when a liquid becomes a gas.

• Both are processes where a material releases (loses) heat energy.

• Both are processes that occur throughout a liquid.

Which of the following expresses a key difference between boiling and evaporation?

• Boiling involves heat added to a liquid but evaporation requires a liquid to lose heat energy.

• Evaporation requires heat energy to be gained by a liquid but boiling boiling requires heat energy to be lost.

• Gas bubbles are observed during boiling, but no bubbles are observed with evaporation.

• Boiling can occur at any temperature of a solid, but evaporation occurs only at the liquid's BP.

A cupful of water and a similar cupful of gasoline were placed onto a table near a window on a warm, sunny day. A few hours later it was observed that both cups had less liquid in them but there was less gasoline left than water. What does this experiment show?

• Gasoline gets hotter than water and the gasoline had a higher temperature than everything around it.

• Some liquids evaporate faster than others.

• Liquids will evaporate only in sunshine.

• Water gets hotter than gasoline and the water had a higher temperature than everything around it.

What is the relationship between phase changes and temperature?

• When a material undergoes a phase change, temperature stays the same.

• Temperature of a material rises when it freezes or condenses.

• Temperature of a material decreases when it melts or boils.

• The relationship between phase changes and material temperature cannot be determined.
