The evil Empire from Star Wars is running a factory that manufactures droids. The factory is powered by a heat engine, which uses a hot reservoir at 650 Kelvin and a cold reservoir at 450 Kelvin, and which (somehow!) operates at the theoretical maximum eciency for a heat engine. The Empire must supply the engine with 1000 kilojoules of heat for every droid it wants to produce. A group of rebels decide to sabotage the factory. They manage to cool the hot reservoir down to a temperature of 500 K, which makes the engine less ecient. After this change, how many joules of heat must the Empire supply to the engine in order to produce one droid?

May 4th is commonly referred to as “Star Wars” day due to the statement of “May the Fourth be with you” and its aural similarity to “May the force be with you.” Within the Star Wars franchise, those who are imbued with the ability to manipulate the force can, after time, manipulate their physiology to reduce their breathing rate and induce bradycardia (reduced heart rate). This can be explained by specialized molecules called “midichlorians” controlling the autonomic nervous system. Assuming...
