Properties of Air Quiz

Air is _____ and capable of being compressed.

• Fluid

• Wet

• Pressurized

• Flowing

What happens to air when it is heated?

• It compresses and shrinks
• It rises
• it expands
• it expands and rises

What can be concluded from the experiment pictured?

• Air has no volume

• Air has mass

• The mass of the black balloon is increasing

• The mass of the meter stick is unreliable

Why can't you lift a piece of newspaper laid flat over a meter stick?

• The newspaper is glued to the table.

• The air pressure above the paper pushes it down.

• The meter stick is too weak.

• The newspaper is too heavy.

Answer explanation

The correct answer is that the air pressure above the paper pushes it down, making it difficult to lift. This pressure creates a force that holds the newspaper against the meter stick, preventing it from being easily lifted.

What happens to a balloon when it is placed in a freezer?

• It expands.

• It shrinks.

• It changes color.

• It pops.

Answer explanation

When a balloon is placed in a freezer, the gas inside it cools down, causing the molecules to move closer together. This results in a decrease in volume, making the balloon shrink.

Hannah, David, and Elijah are conducting a science experiment. They take a balloon filled with air (a volume of gas) and squeeze it into a smaller space. What happens to the particles of gas inside the balloon?

• The number of particles increases

• The particles become smaller in size

• The particles move farther apart

• The particles are pushed closer together

The balloon on the bottle in the hot water demonstrates

• air is affected by temperature

• air exerts presure

• air has mass

• air can be compressed

The air surrounding Earth is held in place by

• friction

• air pressure

• gravity

• heavy clouds
