Hi everybody! I'm new to this forum and i have a question i hope someone

of u can answer...

If i have a cylinder (made of plastic or some other light weight material) 1 meter long with an area of 1 dm2 that would be 10 liters right?

Now, if i place the cylinder vertical and place a 8 kg piston on top of it (inside it on the upper end..), how much will the piston compress the air?

Will it compress it to a volume less than 8 liter? If so, then the construction

will sink if put in water right?

If i let it sink to say 3-4 meter then turn the construction up side down, then

the light weight cylinder will pull upward and the heavy piston will pull downward making the air decompress.

Will it decompress enough to make the contruction move up to the surface again ?

Hope u understand the scenario....

Thanks for your reply :)
