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.
