4/29/2016 11:55 PM 4 @Time Remaining: 36 M 40S Gradebool Question 3 of 5 Map ehi quenstion wos wwitmen by Sean Cordhy at Walters State Community College A cylinder with a moveable piston inside it holds a volume of air of 0.115 m3 at a pressure of 25.5 kPa. The pison inside moves, 30 ng the volume to 0.925 m3, although the temperature of the gas does not change. (See the diagram at right.) 20 Answer the three questions below, using three significant figures 10 Part A: This gas process would be classified as what? (Pick the correct answer.) O An adiabatic process O An isothermal process O An isochoric process O An anachronistic process O An isobaric process 0.5 1.0 Part B: Consider any work or heat flow occuring with this process. (Pick all the statements that are correct.) There must be heat entering the gas somehow. There must be heat leaving the gas somehow. There is no heat entering or leaving the gas. Something is performing work on the gas. O Previous Next Save And Exit

Explanation / Answer

(ANS) : part -A :   an isothermal process

             part -B : There must be heat entering the gas

                            some thing is performing work on the gas

            part - B : There must be heat entering the gas somehow

                           some thing is performing work on the gas

                           The gas is performing work some how

                          The internal energy remains un changed during this process

     PART - C : from graph at the end of the process the pressure is 3 k Pa
