How can it be proven that air has mass????

Question

please be an experiment!!!!!!!!!!

Answer 1

Find some scientifically precise scales.

1. Weigh a balloon.
2. Blow up the balloon.
3. Weigh the balloon again.

The change in weight will indicate a change in mass.
(It must indicate a change in mass because acceleration due to gravity is constant.)

Answer 2

Get an air tight vessel and use a vacuum pump to remove all of the air from the vessel. Weigh the vessel empty. Then allow the vessel to fill with air and weigh it again. The difference between the two weights is the mass of air inside the vessel.

Answer 3

Using a very sensitive scale, weigh a container filled with air. Seal the container air tight and extract the air with a vacuum pump. Now re-weigh the container. The difference in weight will be the mass of the air.

Answer 4

It can empirically be shown that the formula PV= nRT holds.

The natural explanation of it is that air contains particles bouncing around in the container. If the mass of the particles were zero, then they could not exert pressure, but inded they do exert pressure.

Answer 5

of course air has mass but not a definite mass
remember gas has no specific shape or volume
=]

Answer 6

when we blow a balloon it bursts.thus air has mass bcoz anything that exerts pressure has mass

Answer 7

if it is easier use two small car tires one that is full of air and the other empty then have your classmates pick them up, they will notice that the inflated tire is heavier, maybe just small car tires will do.

Answer 8

Yes, it does. I've included a link that you might find interesting. Don't know what experiment you can do, but you might get some ideas.

Answer 9

take a ride in an airplane or go into some pressurized chamber and you can feel it.
