Question

Describe an activity by which you can show that air has weight.​

Answer 1

Explanation:

Let us prove with our experiment that air has mass and takes up space. In the balloon balance experiment, we are blowing up balloons. When blow-up balloons, the air is entering inside them and making the balloons expand. So, this shows that the air occupies space which eventually proves that it has weight.

And when we tie the balloons to the scale with measurements and deflate one of them, the balance tilts i.e., the side attached to the inflated balloon will be on the lower side, and the side with deflated one goes upwards.

The deflated balloon loses its weight. And because of weight, the inflated balloon goes down, and the deflated one goes up on the scale. Using this, we can prove that air takes up space and has mass.

Answer 2

Move the balloons along the scale to balance the scale, slowly allow the air from the balloon A to escape
