The internal energy of an ideal diatomic gas corresponding to volume ' V ' and pressure ' P ' is 2.5 PV. The gas expands from 1 litre to 2 litre at a constant pressure of \(10^5 \mathrm{~N} / \mathrm{m}^2\). The heat supplied to a gas is
- A 350 J
- B 300 J
- C 250 J
- D 200 J
Answer & Solution
Correct Answer
(A) 350 J
Step-by-step Solution
Detailed explanation
\(\begin{array}{ll} & Q=\Delta U+W \\ \therefore & Q=2.5 \mathrm{PV}+\mathrm{PV}=3.5 \mathrm{PV} \\ \therefore & \mathrm{Q}=3.5 \times 10^5=350 \mathrm{~J}\end{array}\)
