Express the change in internal energy of a system when iii) w amount of work is done by the system and q amount of heat is supplied to the system. What type of system would it be?

Text Solution

Verified by Experts

The system is dosed system
Mathematical form
`triangleU =q-W" "triangleU= "Change in internal energy"`
q=heat supplied
W =Workdone by the system.
