compressing air

Asked by grg99 in Math & Science

Tags: air, compressing

Let's say we have a kilogram of air compressed to 2000PSI.

How much energy is released pushing up a piston, until the pressure is down to 500PSI?

Assume the air cools off as expected, no heat in our out from the vessel sides.

Thanks,

grg
