A gas expands from a volume of 2.00m^3 to 6.00m^3 and does 6912 joules of work against a constant outside pressure. Calculate this outside pressure in Pa.
The answer is 1730 Pa, but I don't know how to get that.
I honestly have no idea where to start or what formulas to use. Please help me.
Work= P*change in volume.
Solve for pressure.
thank you very much
