true or false

The SI and Cl engines are both internal combustion (1C) engines. The efficiency of an ideal Otto cycle is higher than the Carnot efficiency between the same temperature limits. In steam power plants, H20 enters the pump as compressed liquid. Under the air standard assumptions, the combustion process is replaced by a heat rejection process In vapor-power cycles, the working fluid remains in gaseous phase throughout the cycle. The ideal Rankine cycle consists of two isentropic and two isothermal processes. In steam power plants, H_2 l enters the boiler as compressed liquid. In steam power plants, H_2 0 leaves the turbine as superheated vapor. Exergy and energy are both properties of a system.
