32 g of `O_(2)` expands from volume `10 dm^(3)" to "10 m^(3)` against pressure of 100 k Pa. Calculate work done.

A

999

B

9990

C

99900

D

999000

Text Solution

Verified by Experts

The correct Answer is:
D
`n=(32)/(32)=1`
`P=100 k P_(a) =100xx103 P_(a)`
`V_(1) =10 dm^(3)=10 (10^(-1) m)^(3)=10xx10^(-3) m^(3)`
`v_(2)=10 m^(3)`
`W= P Delta V=100 xx10^(3) xx (10-10xx10^(-3))`
`=100xx10^(3)xx10(1-10^(-3))`
`=(1-0.001)xx10^(6)`
`=9.99xx10^(5)`
