Glow Up: Physical Properties

Describe an experiment you could conduct to demonstrate that air is made up of tiny particles that are too small to be seen. How does this experiment provide evidence that air takes up space and has mass?

• Place an inflated balloon in water to see if it floats.

• Get the mass of a deflated balloon, then the mass it again after inflating it.

• Observe the movement of a feather in the wind.

• Shake a closed water bottle and listen for sound changes.

What does the displacement of 75 ml of water by the egg tell you about the egg's volume, and how does this affect the water level in the container?

• The egg’s volume is 75 ml, and the water level rises by 75 ml due to the displacement.

• The egg’s volume is greater than 75 ml, and the water level decreases by 75 ml.

• The egg’s volume is 75 ml, but the water level remains unchanged because the egg is floating.

• The egg’s volume is less than 75 ml, and the water level stays the same due to the displacement.
