A system is provided with 50 J of heat and the work done on the system is 10J .What is the change in internal energy of the system in joules ?

A

60

B

40

C

50

D

10

Text Solution

Verified by Experts

The correct Answer is:
D
Q=50 J
` W=10J` (because Work is done on the system )
According to First law of thermodynamics,
`DeltaU=Q+W`
`=50+10
