An ideal gas is taken through quasi static process described by  P=αV2, with α=5.00atm/m6. The gas is expanded to twice  its original volume of  1m3 how much 
work is done by the gas in expanding gas in this process?
 

a
1.18MJ
b
2.18MJ
c
1.28MJ
d
3.18MJ

detailed solution

Correct option is A

W=∫if pdvW=∫if αV2dV=13αVf3−V13∣Vf=2Vi=2(1.00)=2.00m3W=135×1.013×105×[23−13]=1.18MJ
