Question

Figure shows a irreversible thermodynamic process mole one mole of gas. How does the work done in process changes with time?

• A. decreases continuously
• B. increases continuously
• C. remains constant
• D. first increases then decreases

Answer 1

Answer: (B)

increases continuously

a irreversible thermodynamic process mole one mole of gas.

The work done of a process is define as the work done =change in pressure pressure *change in volume

$W=d\left(PV\right)$

in the graph since the pressure and volume are increasing continously

hence the change in pressure and volume is positive and increasing hence work done is increasing positive
