Current Question (ID: 11013)

Question:

$\text{A given mass of gas expands from state } A \text{ to state } B \text{ by three paths 1, 2 and 3, as shown in the figure. If } W_1, W_2 \text{ and } W_3 \text{ respectively be the work done by the gas along the three paths, then:}$

Options:

1. $W_1 > W_2 > W_3$
2. $W_1 < W_2 < W_3$ (Correct)
3. $W_1 = W_2 = W_3$
4. $W_1 < W_2 = W_3$

Solution:

$\text{Hint: } W = \int P\Delta V$ $\text{Explanation: The area of pressure versus volume graph gives work done. Therefore, the correct order of the work done by gas is } W_1 < W_2 < W_3\text{.}$ $\text{Hence, option (2) is the correct answer.}$
