I need the answers for d-f but please also answer a-c as well.
Transcribed Image Text:An ideal gas of N diatomic molecules (y = 1 +
2/5 = 7/5) undergoes three consecutive
transformations, as diagrammed below.
a) In terms of po, Vo, and N, find the
temperatures T1, T2, T3 at all three "corners"
of the cycle.
b) In terms of Vo and y, find the volume V3 at
point 3 of the cycle.
• The transformation 1→2 is isobaric.
• The transformation 2--3 is adiabatic.
• The transformation 3→1 is isothermal.
c) In terms of po and y, find the pressure pa at
point 3 of the cycle.
d) For each of the transformations 1→2, 2-3,
3-1, find the changes in internal energy
ΔΕ2 , ΔΕ_3, ΔΕ31.
