Show hintHide hint
Think of the processes involved in steam generation.
Question 2.
What does COP stand for?
Show hintHide hint
It's a measure used primarily in refrigeration systems.
3Question 3.
What does the Rankine cycle primarily involve?
- Cooling
- Heating and expansion

Show hintHide hint
Think about the processes involved in the cycle.
4Question 4.
True or False: Supercritical cycles achieve higher efficiency due to a distinct phase change.
- True
- False
Show hintHide hint
Consider the nature of phase changes.
Question 5.
