SUMMARY

The discussion centers on solving a thermodynamic cycle problem involving a mole of ideal gas initially at a temperature of 300K. The gas undergoes isobaric expansion, tripling its volume, followed by isochoric cooling back to the initial temperature. The work done by the gas is calculated using the formula A = P * ΔV, leading to the conclusion that A = 2 * P * V1 = 2 * quantity of moles * R * 300, confirming the correctness of the approach taken by the participant.

PREREQUISITES
  • Understanding of ideal gas laws
  • Knowledge of thermodynamic cycles
  • Familiarity with the concepts of isobaric and isochoric processes
  • Proficiency in using the ideal gas constant (R)

Homework Statement



A mole of ideal gas with a temperature T1=300K is expanded isobarically until its volume is tripled .Then the gas gets colder isochorically until we reach the temperature we had in the beginning 300 K.Find the work of the gas.
Hint : We have a thermodynamic cycle .

Homework Equations



A=p* DeltaV=quantity of moles * R* deltaT

The Attempt at a Solution


Find A=P *3V1-V1=p*2v1=2*P*V1=2*quantity of moles*R*300...Is this correct? Show me ur solution

Welcome to PF, Elaia06! :smile:

Yep. That looks correct to me.

Btw, your problem states that the quantity of moles is one.
And do you know a value for R?
