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.
Use the Periodic Table to help answer this question.
Which 2 elements will have similar physical and chemical properties?
Br & Se
Ca & Mg
Ge & Se
K and Mg
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.
