1. Homework Statement
A balloon behaves such that the pressure is P = CV3
where C
= 100 kPa/m3
. The balloon is blown up with air from a starting volume of 1 m3
to a volume
of 3 m3
. Find the work done by the air.
2. Homework Equations
W=PdV
3. The Attempt at a Solution
What I tried is simply trying the above solution by multiplying the P which is given by P=CV^3 by the change in volume
so i got
W=(CV^3)(Vf-Vi)
I then realized I had no idea what would the V in this equation be, can someone tell me if I am even doing this question right and if I am how I can determine the V?
Thanks
