Q3.4]Consider a perfect gas contained in a cylinder and separated by a frictionless adiabatic piston into two sections A and B. All changes in B is isothermal; that is, a thermostat surrounds B to keep its temperature constant. There is 2.00 mol of the gas in each section. Initially, TA = TB = 300 K, VA = VB = 2.00 dm³. Energy is supplied as heat to Section A and the piston moves to the right reversibly until the final volume of Section B is 1.00 dm3. Calculate (a) ASA and ASg, (b) AS of the total system and its surroundings. If numerical values cannot be obtained, indicate whether the values should be positive, negative, or zero or are indeterminate from the information given. (Assume Cy.m= 20 J K-' mol1.)

![Q3.4]Consider a perfect gas contained in a cylinder and separated by a frictionless adiabatic piston into two
sections A and B. All changes in B is isothermal; that is, a thermostat surrounds B to keep its temperature
constant. There is 2.00 mol of the gas in each section. Initially, TA = TB = 300 K, VA = VB = 2.00 dm³. Energy is
supplied as heat to Section A and the piston moves to the right reversibly until the final volume of Section B is
1.00 dm3. Calculate (a) ASĄ and ASg, (b) AS of the total system and its surroundings. If numerical values cannot
be obtained, indicate whether the values should be positive, negative, or zero or are indeterminate from the
information given. (Assume C.,m = 20 J K-' mol-!.)](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F8c46c0c1-66e3-411f-b1c6-eb3b1b151e63%2Fce42b607-8d96-4236-a423-466c961fe833%2Fv0nl2jh_processed.jpeg&w=3840&q=75)
