21.3 moles of a diatomic ideal gas undergo three steps:

  • A to B is an isobaric (constant pressure P1 = 4.15x106 Pascal) expansion from volume V1 = 0.0609 m3 to V2 = 0.934 m3.
  • B to C is isochoric (constant volume)
  • C to A is isothermal (constant T).

During the isobaric expansion from A to B: find Q, the heat transferred, in Joules. Give your answer in scientific notation.

NOTE: A positive sign means heat has been added; a negative sign means heat has been lost.

Answer #1
  • Given-- number of moles (n) =21.3 mol
  • diatomic gas, this means that degree of freedom (f) = 5.(nothing is mentioned about bond, so we will take rigid bond)
  • heat is given to the system. Therefore, dQ is positive.
  • Kindly give your feedback.
  • Thank you.
  • All the best.

28 moles of an ideal gas with a molar specific heat at constant volume of cv=3.2R is initially in state "A" at pressure 73390 Pa and volume 1.0 m3. The gas then expands isobarically to state "B" which has volume 2.6?3m3. The gas then cools isochorically to state "C". The gas finally returns from state "C" to "A" via an isothermal process. What is the adiabatic constant γ for this gas? What is Q during the expansion from "A" to...

3.0 moles of an ideal gas are subjected to the following processes. First the volume is tripled in an isobaric process. Then it undergoes an isothermal process to a pressure of 9.0 kPa. The volume is then cut in half in another isobaric process after being tripled. Finally, it returns to the original state in an isochoric process. (a) Draw a PV diagram of the cycle. Label each state (vertex) with a letter (A, B, …) and each transition with...
