0.06 moles of a monatomic gas undergoes the cycle A ⟶B⟶C⟶A as
shown on the P-V diagram below.
In the transition A⟶B the gas expands adiabatically and the
temperature drops from 600K to 400K. What is △U for this
transition? What is the work done on the gas? (This is the answer
to (a) in the table below)
During the transition B⟶C, the volume decreases from
2x10-3 m3 to 1x10-3 m3
at constant atmospheric pressure (isobaric). What is the work...
