By operating a reversible heat engine with an ideal gas as the working substance in a Carnot cycle and measuring the ratio QL/QH, we can calculate:
a. n, the number of moles of the ideal gas
b. the ratio VL/VH of the volumes of the ideal gas.
c. the ratio PL/PH of the pressures of the ideal gas.
d. the ratio PLVL/PHVH of the products of volumes and pressures of the ideal gas.
e. the value of Avogadro's number.
