Answer:
(a)
(b)
Explanation:
Hello.
(a) In this case, since the initial volume is 18.5 dm³ and the final volume is 21 dm³ (18.5 +2.5), we can compute the work at constant pressure as shown below:
Which is negative as it expands against the given pressure.
(b) Moreover, of the process is carried out reversibly, the pressure can change, therefore, we need to compute the work via:
Whereas the moles are computed from the given mass of argon:
Thus, the work is:

The choices for this question can be found elsewhere and as follows:
short hill.
tall hill.
tightly coiled spring.
<span>stretched-out spring.
</span>
I think the best answer is the third option. A high amplitude sound wave can best be compared to a tightly coiled spring. <span>A </span>high<span> energy </span>wave<span> is characterized by having a </span><span>high amplitude.</span>
