This is a past exam question, not a homework question. I don't have the solutions, so I wanted to check if I had it right.

"An isolated cylinder contains one litre of monatomic ideal gas at 300K and pressure of 10^5 N/m^2. At one end there is a massless piston with surface area 0.01m^2. The cylinder is compressed very fast (non-quasistatically) by the piston exerting an external force of 10000N. The piston moves by 1 millimetre."

So that is the set up. I'm interested in the work done (on the system), and heat added.

So if is work doneonthe system, then is this right?

So ?

I'm having a bit of a mental block when it comes to the heat added, though. If anyone could help me with that?

After I get that i need change in internal energy and change in entropy, so that would just be and yes?

Thanks in advance
