The gas absorbs 150 J heat and is simultaneously compressed by a constant external pressure of 1.50 at from 8L to 2 L in volume. Hence, `Delta U` will be:

A

`-812J `

B

`1062J`

C

`1012 J`

D

`912 J `

Text Solution

Verified by Experts

`DeltaU = q + W, q = 100 J, W = 1. 5 xx 9 = 9 L atm = 911.9 J implies DeltaU = 1011. 9 J`
