27. A sample containing 3.00 moles of a monatomic ideal gas is taken from state X(PX = 1.00 atm, VX=5.0 L) to state Y (PY = 1.00 atm, VY = 35.0 L). For thisprocess, assuming that the external pressure is constant and equals the finalpressure of the gas. Which of the following statements is correct? (gas constant R = 8.314 J·mol-1.Kl-1)
(A)This is an adiabatic process.
(B)The process is isothermal.
(C)AE (the change of internal energy) = -4.56 kJ
(D)AH (the change of enthalpy) = 7.60 kJ
(E)The work of 3.04 kJ flows into the system.
