Air Mass & Volume

Why does air have mass?

• Air has mass due to its temperature

• Air has mass because of its smell

• Air has mass due to the presence of molecules and atoms within it.

• Air has mass because of its color

What is the property of air that allows it to push things?

• Density

• Volume

• Pressure

• Temperature

How can you prove that air has mass?

• Inflate a balloon and weigh it before and after inflation to observe the increase in mass.

• Measure the weight of a deflated balloon and compare it to the weight of an inflated balloon

• Blow air into a container and observe if the container becomes heavier

• Drop a feather and a rock in a vacuum chamber to observe their fall rate

What happens when you blow up a balloon with air?

• The balloon disappears.

• The balloon turns into a rubber ball.

• The balloon expands and inflates.

• The balloon shrinks and deflates.

How does air take up space?

• Air doesn't take up space, it's invisible

• Air takes up space due to the mass and volume of its molecules.

• Air takes up space because it's magical

• Air takes up space due to its color

Can you see air? Why or why not?

• Yes, air is visible

• Air is transparent so it can be seen

• Only if it's colored

• No, we cannot see air.

What tool can you use to measure the mass of air?

• Thermometer

• Anemometer

• Barometer

• Hygrometer

Explain why a balloon gets bigger when you blow air into it.

• The balloon gets bigger because the increased air pressure inside pushes against the balloon's elastic material, causing it to expand.

• The balloon gets bigger because it absorbs the air molecules and grows in size.

• The balloon gets bigger because of the color of the balloon.

• The balloon gets bigger due to the gravitational pull of the Earth.

How does air pressure change with altitude?

• Air pressure increases with altitude.

• Air pressure decreases with altitude.

• Air pressure fluctuates randomly with altitude.

• Air pressure remains constant with altitude.

Why is it important to understand that air has mass and volume?

• The mass and volume of air have no impact on the environment

• Air has no mass or volume

• Understanding air's mass and volume is irrelevant in scientific studies

• It is important to understand that air has mass and volume to comprehend various scientific principles and phenomena.
