A system is provided with \(50 \mathrm{~J}\) of heat and the work done on the system is \(10 \mathrm{~J}\). What is the change in internal energy of the system in joules?
- A 60
- B 40
- C 50
- D 10
Answer & Solution
Correct Answer
(A) 60
Step-by-step Solution
Detailed explanation
From first law of thermodynamics, \(\Delta E=Q+W\) Since, heat is provided to the system, \(Q=+50 \mathrm{~J}\) and work is done on the system, \(W =+10 \mathrm{~J}\) \(\therefore \Delta E =50+10=60 \mathrm{~J}\)
