Question

Figure shown four thermodynamical process to which a gas sample may be subjected. The isobaric and isothermal curves are

  1. IV and III    
  2. II and IV    
  3. I and III    
  4. II and III    

The correct answer is: IV and III


    Curve IV is parallel to volume axis. It represents isobaric curve. Out of II and III, slope of III is smaller. Therefore, III curve represents an isothermal curve
