In a process 605 J heat is absorbed by the system and 380 J work is done by the system on surrounding. What is the value of \(\Delta \mathrm{U}\) ?
- A -225 J
- B -985 J
- C +225 J
- D +985 J
Answer & Solution
Correct Answer
(C) +225 J
Step-by-step Solution
Detailed explanation
\(\begin{aligned} \Delta U & =q+w \\ & =605+(-380) \\ & =225 \mathrm{~J}\end{aligned}\)
