Hi Brenda and all!

for my qn I googled and find the answer.Brenda u r right that amount of gas still be the same but volume will be reduced.So the provided answer is wrong cos talking about volume not mass.I want to share that i found in the web with u all.Thanks to WCW and Champion for ur kindness.

Compressing Air

Danny watched his friend Joe, who was playing with the air pump of his bike. He put his finger on the pump’s spout, and pressed its piston. “Interesting”, said Danny, “this is the first time I have noticed this”.
“Noticed that?” said Joe.
When you press the air in the pump with the spout blocked, you reduce the volume of the air in it. I wonder why...

Have you ever thought why is it that air can be compressed to occupy less space?

Perform the following experiment:
Experiment:
Take a syringe (without the needle in the end), and draw air into it. Now seal its end with a cork, and press the syringe’s piston. Since the syringe is sealed, the air cannot escape, so the volume of the gas is reduced.
Attention: the more the air is compressed (as its volume becomes smaller), the harder it gets to compress it!

How can we explain the phenomenon of air being reduced to a smaller volume?

In order to answer that question, take a look at the following claims:

1.\tMatter is comprised of tiny particles, which we are unable to see, and between these particles there are spaces. The spaces between the particles contain nothing, not even air; the space between particles is a vacuum. Particles are in constant movement within the vacuum, in all directions.

2.\tMatter is continuous- matter is not made of tiny particles, but is one integral unit. Matter can expand and contract, depending on the environmental conditions it is placed in.

Hi smartmummy,

:thankyou: for sharing and this explanation is really wonderful! :celebrate:
