Dixie Brown · Answer 1

A decrease in it's operating temperature would make a heat engine less efficient. This is because in order to operate, a heat engine needs to be hot and maintain that temperature.

Alana Blevins · Answer 2

D

A decrease in operation temperature will decrease the temperature difference and reduce efficiency.
