A Carnot cycle is composed of two isothermal steps and two adiabatic steps. 8.0 moles of an ideal monoatomic gas are used as the working substance in a Carnot engine a = b d = a. The volume V} is 4 times larger than V,. The engine's efficiency is 20%. The engine runs between two heat reservoirs; the hot reservoir used by the engine has temperature 1000K. a) During which step(s) is heat added to the gas? b) Determine the total heat added to the gas in one cycle, Only consider heat added to the gas, do not Consider heat expelled or removed from the gas. c) What is the ratio of the multiplicity (# of microstates) of the gasin State d to the multiplicity in state c. Express your result as 10%. In other words, wd /we = 10* determine a
