Academics

A heat engine using 1 mole of an ideal gas follows the Carnot Cycle ABCD, where the transitions are:

a) A----B, which is an isothermal expansion at a temperature of 127 oC during which the volume is doubled

b) B---C, which is an adiabatic expansion with a final temperature of 27 oC.

c) C---D, which is an isothermal compression to one half of the volume at point C.

d) D---A, which is an adiabatic compression with a final temperature of 127 oC.

How much heat in kJ is absorbed during the transition AàB?

How much heat in kJ is released during the transition CàD?

What is the thermal efficiency of the engine in %?
