Question

We can easily see liquids and solids around us, but most gases aren’t visible. We can’t see the air around us, but it is still made of atoms that constantly move around freely in space. How can we tell?
Task: You have the following materials: balloons, water bottles, rulers and a balance. Design an experiment to show that air is matter by showing that air has mass and takes up space.

Answer 1

Based on the results of the experiment, it can be concluded that air is matter as it has mass and occupies space.

Experiment to show that air has mass and takes up space.

Materials: balloons, water bottles, rulers and a balance.

Aim: To prove that air has mass

Procedure: Measure the mass of the empty balloon and record.

Next fill the balloon with air and record.

Result: The mass of the balloon increases showing that air has mass.

Aim: to prove that air occupies space.

Procedure: Dip the bottle in an upright position into water.

Result: Water fills up the bottle as air escapes.

Procedure: Next, dip the bottle in an inverted position in water.

Result: Water cannot enter the bottle as there is no way for air to escape.

This proves that air occupies space.

Therefore, from the results of the experiment, it can be concluded that air is matter as it has mass and occupies space.
