Suppose that a class CalendarDate has been defined for storing a calendar date with month, day and year components. (In our sect
ion handout, the class was called Date, but we have renamed it here because Practice-It uses a class named Date for other purposes.) The class includes the following members:

Answer:
Yes
Explanation:
Given Data
Temprature of source=750°c=1023k
Temprature of sink =0°c=273k
Work produced=3.3KW
Heat Rejected=4.4KW
Efficiency of heat engine(η)=
and
Heat Supplied
η=
η=42.85%
Also the maximum efficiency of a heat engine operating between two different Tempratures i.e. Source & Sink
η=1-
η=1-
η=73.31%
Therefore our Engine Efficiency is less than the maximum efficiency hence the given claim is valid.
