If \(150 \mathrm{~J}\) of heat is added to a system and the work done by the system is \(110 \mathrm{~J}\), then change in internal energy will be
- A 150 J
- B 110 J
- C 260 J
- D 40 J
Answer & Solution
Correct Answer
(D) 40 J
Step-by-step Solution
Detailed explanation
According to the first law of thermodynamics, the change in internal energy \(\Delta U\) is given by the equation: \(\Delta U = Q - W\) where \(Q\) is the heat added to the system and \(W\) is the work done by the system. Given values are \(Q = 150 \text{ J}\) and…
