Jacob took an empty water bottle and put the lid on it. He then put the water bottle into a boiling water bath. After 5 minutes, Jacob removed the bottle and immediately placed it in a cold water bath.

Which of the following BEST explains what Jacob observed?

• The water bottle collapsed because the volume increased as the temperature decreased.

• The water bottle collapsed because the volume decreased as the temperature decreased.

• The water bottle expanded because the volume increased as the temperature decreased.

• The water bottle expanded because the volume decreased as the temperature decreased.

Using the data on the periodic table provided, which of the following statements is TRUE?

• The number of valence electrons increase going from left to right because more electrons are added on the outermost energy level.

• All of the transition metals are solids because they have more in common with metals than they do with nonmetals.

• The noble gases are found on the right side of the periodic table because that is where metals are found.

• All metals form negative ions because they give up electrons to form bonds in compounds.

A glass of water is at room temperature in an isolated system. What will happen if one ice cube is added to the system?

• 
  Heat will be removed from the system, causing the liquid water to lose some molecular motion but retain its state.

• 
  Heat will be removed from the system, causing the liquid water to lose some molecular motion and change state.

• Heat will be added to the system, causing the liquid water to gain some molecular motion but retain its state.

• Heat will be added to the system, causing the liquid water to gain some molecular motion and change state.
