Question
Figure shows two paths through a gas can be taken from the state A to the state B. The work done by the gas which is higher than the other is :-
Options
A.1.5 J
B.2 J
C.0.45 J
D.0.6 J
Solution
ᐃWAB = Area under A → B bounded by volume axis.
= 10 × 103 (25 - 10) × 10-6 +
(25 - 10) × 10-6 × 20 × 103 = 0.15 + 0.15 = 0.3 J.
In path A → C → B = 30 × 103 (25 - 10) × 10-6 = 0.45 J.
= 10 × 103 (25 - 10) × 10-6 +
(25 - 10) × 10-6 × 20 × 103 = 0.15 + 0.15 = 0.3 J.In path A → C → B = 30 × 103 (25 - 10) × 10-6 = 0.45 J.
