Question 1
An ideal heat engine can have an efficiency of 1 if the temperature of the low temperature reservoir is
◦
0 K.
◦
0°C.
◦
0°F.
◦
0°R.
◦
the same as the temperature of the heat source.
Question 2
By operating a reversible heat engine with an ideal gas as the working substance in a Carnot cycle and measuring the ratio Qc/Qh, we can calculate
◦
n, the number of moles of the ideal gas.
◦
the ratio Vc/Vh of the volumes of the ideal gas.
◦
the ratio Pc/Ph of the pressures of the ideal gas.
◦
the ratio PcVc/PhVh of the products of volumes and pressures of the ideal gas.
◦
the value of Avogadro's number.
