A system does 200 J of work and at the same time absorbs 150 J of heat. The magnitude of the change in internal energy is __________ J. (Nearest integer)

Text Solution

Verified by Experts

The correct Answer is:
50
q =150 Joules
W = -200 Joules
`DeltaE = q + w` (First law of thermodynamics)
`DeltaE = 150 + (-200)`
`DeltaE = - 50` Joule.
