Three moles of an ideal gas expanded spotaneously into vacuum. The work done will be

A

infinity

B

`10 J`

C

zero

D

`5 J`

Text Solution

Verified by Experts

The correct Answer is:
C
If an ideal gas expand against vacuum, the irreversible expansion is called free expansion. As `P_(ext)=0`, therefore, for reversible as well as irrversible expansion, work done `=0`
`W_(irre)=-P_(ext)DeltaV=0xxDeltaV=0`
