2kg of water is converted into steam by ...

`2kg` of water is converted into steam by boiling at atmospheric pressure. The volume changes from `2xx10^(-3) m^(-3)` to `3.34 m^(3)` . The work done by the system is about

A

-340 KJ

B

-170 KJ

C

170 KJ

D

340 KJ

Text Solution

Verified by Experts

The correct Answer is:
D
Work done (W) = `P Delta V`
`=1.01xx10^5 (3.34-2xx10^(-3)) = 340 KJ`
