A gas in a closed container undergoes the cycle \(\mathrm{ABCA}\) as shown in the figure. The net heat absorbed by the gas after it has completed 10 cycles is
- A \(-1.5 \mathrm{~kJ}\)
- B \(+1.5 \mathrm{~kJ}\)
- C \(+2.25 \mathrm{~kJ}\)
- D \(-2.25 \mathrm{~kJ}\)
Answer & Solution
Correct Answer
(A) \(-1.5 \mathrm{~kJ}\)
Step-by-step Solution
Detailed explanation
\(\Delta \mathrm{Q}=\Delta \mathrm{W} \quad[\because\) process is cyclic \(]\) \(=-\left[\frac{1}{2} \times 15 \times 20\right] \times 10 \quad[\because\) no. of cycles \(=10]\) \(=-1500 \mathrm{~J}\) As cycle is anti-clock wise. So \(\Delta \mathrm{W}\) is -ve therefore,…
