250 J of work is done on the system and at the same time 100 J of heat is given out. What is the change in the internal energy ?
Given `w = 250J " "["Work done on the system, " wgt0 "Heat given out of the system, " q lt0] `
`q=100J`

Text Solution

Verified by Experts

`DeltaU=q+w`
`=(-100)+(+250)=50`
`DeltaU=+50J`
