Date: 12/07/2021

DON'T MISS THE 4 PRACTICE PROBLEMS AT THE END. HOW TO IDENTIFY AND TACKLE IRREVERSIBLE IDEAL GAS PROCESSES FROM A GIVEN INFORMATION IN THE PROBLEM.
Q : Two vertical conducting cylinders A and B of different cross sections are connected by  a thin  tube as shown. An ideal gas is trapped in the cylinders by two airtight pistons of masses l.0 kg and 2.0 kg respectively. Initially the pistons are at the same height 40 cm above the base of the cylinders. If an additional mass of 10 g were gently placed on the piston in the cylinder A, which of the following statements correctly describe the new steady state ultimately reached.
 (a) Pressure of the gas has been increased.   
 (b)Pressure of the gas remains unchanged.     
 (c) Height difference between the pistons becomes 30 cm.    
 (d)Height difference between the pistons becomes 60 cm.

THERE ARE MULTIPLE METHODS TO SOLVE SUCH PROBLEMS ON THE CONCEPT OF "IRREVERSIBLE IDEAL GAS PROCESSES , BUT IN THIS VIDEO WE PRESENT AN EXAM ORIENTED APPROACH FOR OBEJECTIVE TYPE QUESTIONS - 15,24 , PASSAGE 30,31 OF CHAPTER - 8 "THERMAL PHYSICS " SOLVED FROM THE BOOK "PATHFINDER PHYSICS"👇
