See diagram 4.

22.8 moles of a diatomic ideal gas undergo three steps:

A to B is an isobaric (constant pressure P1 = 5.25x106 Pascal) expansion from volume V1 = 0.0248 m3 to V2 = 0.956 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.DIAGRAM 1 DIAGRAM 2 wire m hinge DIAGRAM 3 DIAGRAM 4 P(Pa) A P1 B m oc C V (m) V1
