Calculate the work, w, gained or lost by the system when a gas expands from 15 L to 45 L against a constant external pressure of
1.5 atm. 1 L × atm = 101 J.
1 answer:
Answer:
Work done by the system = 4545 J
Explanation:
The expression for the calculation of work done is shown below as:
Where, P is the pressure
is the change in volume
From the question,
= 45 - 15 L = 30 L
P = 1.5 atm
Also, 1 atmL = 101 J
So,
(negative sign implies work is done by the system)
<u>Work done by the system = 4545 J</u>
