Q. An ideal gas expands along the path AB as shown in the p-V diagram. The work done is
A) $4 \times 10^{4}J$
B) $1.2 \times 10^{5}\ J$
C) $2.4 \times 10^{5}J$
D) None of the above
Explanation
(b) Work done =area of trapezium
$= \frac{1}{2} \times \left( 8 \times 10^{5} + 4 \times 10^{5} \right) \times 0.2 = 1.2 \times 10^{5}J$
