Science Test Prep: What is Matter

Given that balloons A and B were identical in size and weight before being filled, what conclusion can be drawn about the air inside them based on the illustration?

• The air in both balloons weighs the same, as they are balanced.

• The air in balloon A is heavier than in balloon B because the balloons are not level.

• The weight of the air cannot be determined since air is weightless.

• The air in balloon B is heavier than in balloon A because the balloons are level.

Which model best illustrates the behavior of gas particles in a balloon?

• Model A is a gas because particles in a gas move freely and are well spaced.

• Model B is a gas because particles in a gas are tightly packed.

• Model C is a gas because particles in a gas are closely arranged.

• None of these models accurately represent gas particles, or all do.

What is the likely outcome if air is added to balloon B while both balloons A and B are initially balanced?

• Balloon B would lower, and balloon A would rise because Balloon B would become heavier.

• Balloon B would rise, and balloon A would lower because Balloon A would be heavier.

• The sides would remain balanced because the added air has no weight.

• Balloons A and B would move up and down until they reached a new balance point.

A student noticed that ice cubes in a tray expanded and rose above the tray's surface after freezing. Which explanation best describes this observation?

• Ice cubes increase in weight and volume, causing them to rise.

• Ice cubes have a lower temperature, causing them to shrink.

• Ice cubes increase in volume, causing them to rise above the tray.

• Ice cubes increase in weight, causing them to rise above the tray.

If a 170-gram popsicle expands as it changes from liquid to solid, describe what happens to the mass.

• The mass will be 170 grams because the ice decreased in size.

• The mass will still be 170 grams because the matter inside did not change.

• The amount of matter increased in size, so the mass will be 190 grams.

• The mass will be 190 grams because the ice increased in size.
