a) Explain the differences between an open system (e.g. a heat exchanger) and a closed system (e.g. a Stirling
engine) in terms of their operation and construction. You may use diagrams and show how the formula for
the first and second law of thermodynamics would be modified for each system
b) Show how the formula for the first law of thermodynamics would be modified for each system.
c) Show how the formula for the second law of thermodynamics would be modified for each system.
