Problem D18: A monatomic ideal gas undergoes the cyclic process shown below. The process is a rectangle in the P-V plane. The gas goes through the following pressure-volume changes: V0P0 &rarr V0n2P0 &rarr n1V0n2P0 &rarr n1V0P0 &rarr V0P0. If the heat into the gas is Qin=n3P0V0/2, what is n3? Note that n1, n2 and n3 are unitless.

n1 = n2 = Input n3:
