Answer:
600
Step-by-step explanation:
Given parameters:
Number that rode in columns =
times the number that rode in rows.
2200 rode in columns
Unknown:
Number of people that rode in rows = ?
Solution:
Let the number of people that rode in columns = C
Let the number of people that rode in rows = R
C =
R
Number of people that rode in rows = 2200;
2200 =
R
11R = 2200 x 3
R = 
R = 200 x 3
R = 600
Number of people that rode in rows = 600
The work done by the gas when the gas expands will be 567.65 ft-lb.
<h3>What is the work done for an isothermal process?</h3>
The Pressure is inversely proportional to the volume.
Let the initial pressure and initial volume be P₁ and V₁, and the final volume be V₂.
Then the work done by the gas will be
WD = P₁ V₁ ln (V₂ / V₁)
A quantity of the gas with an initial volume of 2 cubic feet and an initial pressure of 700 pounds per square foot.
The gas expands to a volume of 3 cubic feet.
Then the work done by the gas will be
WD = 700 x 2 x ln (3/2)
WD = 1400 x 0.405
WD = 567.65 ft-lb
The work done by the gas when the gas expands will be 567.65 ft-lb.
