Thermodynamics problem: help needed!
Gas in a container expands at a constant pressure of 95 atmospheres. Find the work done by the gas if the initial volume is 5 L and the final volume is 10 L. Answer in units of Joules.
I thought this problem was straight-forward, but I missed it.
I converted 95 atmospheres into Pascals.
95 X 1.013e5 PA = 9623500
I then converted L into meters ^3.
Vi = 0.5 m^3
Vf = 1 m^3
With the units converted, I used the equation W = P(Vf - Vi) and got the answer 4811750 Joules. The answer is incorrect, or so I believe.
Where did I go wrong?
