When exposed to very high temperatures, metals like iron can be turned into fluids that flow and can be poured into molds. What happens within the iron to allow it to flow?

• The structural energy of the solid decreases, and the particles begin to collide with high frequency.

• The structural energy of the solid increases, and the particles begin to slide past each other.

• The particles collide at an increasing rate until reaching equilibrium structural energy.

• The particles vibrate about equilibrium in an effort to minimize structural energy.

Read the text about an experiment with bottled soda. When soda bottles are sealed in a factory, the bottles are all the same temperature with the same pressure of gas inside. A student decides to perform an experiment to determine what changes will result from adjusting the temperatures of two sealed soda bottles. One bottle of soda is heated, while the other is cooled. Which statement describes a result of the experiment?

• The total volume of gas in the cooled bottle increased.

• The total volume of gas in the heated bottle increased.

• The pressure of the gas increased in the bottle that was cooled.

• The pressure of the gas increased in the bottle that was heated.

The air pressure inside an automobile tire is lower during cold weather than during warm weather. The lower air pressure is most likely due to

• salt on the roads producing a decrease in tire volume.

• a decrease in the speed of the air molecules in the tire.

• cold air in the tire producing an increase in tire volume.

• an increase in molecular potential energy of the air molecules in the tire.

Read the passage about Ivory soap. Ivory soap floats in water because it is less dense than water. When Ivory soap is put into a microwave oven and cooked for 25 seconds, it will expand and fill up the microwave. What is the most likely reason the Ivory soap expands when heated?

• The particles in the Ivory soap expand when the temperature increases.

• The increase in temperature causes a chemical reaction to make more soap.

• The air spaces in the soap heat up and cause the soap particles to increase in number.

• The volume of gas in the spaces of the Ivory soap expands when the temperature increases.

A balloon is filled with helium and released. The pressure decreases as the balloon rises. Which will most likely happen to the balloon as it rises?

• The balloon will expand as it rises since the volume will increase.

• The balloon will shrink as it rises since the volume will decrease.

• The balloon will leak gas as it rises and the volume will decrease.

• The balloon will not change as it rises because the volume is constant.

How does the molecular motion of a substance change when it goes from liquid to solid?

• The molecules gain energy, and their relative motion increases.

• The molecules lose energy, and their relative motion increases.

• The molecules gain energy, and their relative motion decreases.

• The molecules lose energy, and their relative motion decreases.

Read the passage about a science experiment that Jacob conducted. 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.

If a gas is at a constant temperature and the pressure increases, what will happen to the volume?

• The volume will increase because it is directly proportional to the pressure.

• The volume will decrease because it is directly proportional to the pressure.

• The volume will increase because it is inversely proportional to the pressure.

• The volume will decrease because it is inversely proportional to the pressure.

What is matter?

• anything that has mass and takes up space

• anything that has volume and takes up space

• study of the properties of mass its changes

• a substance that cannot be broken down further and retain its properties
