Answer 2

Answer: A physical balance, an air pump and two identical footballs

Procedure

Keep two identical deflated footballs

at the two pans of a physical balance.

Find the difference in weight.

Now, pump air in one of the footballs.

Place each of them on the pans of

the physical balance again.

5. Now, find the change.

We find that the inflated football has more weight than the deflated one. This proves that

air has weight. The pressure of the compressed air in the football is higher than the air

pressure before pumping it.
