How to Calculate change in volume produced by a piston?

[SteamKing]

Awesome! Thank you very much! So now that's all figured out how would I multiply that by the atmospheric pressure, 0.25 A t m? Would I convert the A t m to scientific notation and then multiply?

It's a little more involved than that.

First, what are the units of work?

BTW, the unit 'atmosphere' is abbreviated 'atm.', not 'a t m'.

I believe that units of work are in Joules. And sorry, I know it's 'atm', not 'a t m', but that's just how my homework had it, so I thought I just would just keep it like that. An error in my homework grammar, I guess.

Yes. But joules are known as derived units in SI, which means they are made up of other fundamental units. What are the fundamental units which make up a joule?

So, once I convert 1700nm to meters, that would be 1.7x10^-6.

Again, you're omitting the units in your answer. 1.7 x 10^-6 in what units?

When you're working problems in physics, it's very important to keep track of the units.

Area of piston=1x10^-16m^2

Can someone convince me that an exercise with such a "piston" is for real ?

Sounds like some sort of nano-machine.
