Which is an accurate statement about the work output of all heat engines?
O When heat flows from the higher temperature reservoir to the lower temperature
reservoir, all
of that heat is converted into work.
O When heat flows from the higher temperature reservoir to the lower temperature
reservoir, some of that heat is converted into work.
Heat engines create mechanical work by making heat flow from a reservoir of
lower temperature to a reservoir of higher temperature.
Heat engines create work output by converting mechanical and electrical energy
into thermal energy.
