An engineer designed an ocean liner that would extract heat from the ocean's waters at T=10 C and reject heat to the atmosphere at T=20 C. He thought
he had a good idea, but his boss fired him. Explain.

Probably because it takes work to pump heat from a cold body (water) to a warmer body (the heat exchanger that is dumping heat into the air at 20 degrees). So the Ocean Liner is using more energy to extract heat from the water, than what it is actually gaining from the water.

Youre losing more heat than your gaining.
Input= 10
Output =20
Input does not equal output.
So the ocean liner would lose heat

heat always moves from a hot source to a cold source. The ?th law of thermodynamics. He should have been fired, what a dumbass.
