## Homework Statement

An ideal refrigerator utilizes a carnot cycle operating between 0 and 25 degrees celsius. To turn 10 kg of water at 0 degrees celsius into 10 kg of ice at 0 degrees celsius,

a) how much heat is exhausted into the room?

b) how much energy must be supplied to the refrigerator?

## Homework Equations

coefficient of performance of carnot refrigerator (Kcarnot): Tc/(Th-Tc)

n (funky n for efficiency thing)=Wout/Qh [but isn't that for engine]

K=Qc/W

## The Attempt at a Solution

I'm guessing part A is Q so I'd have to find that somehow. And, for part B I think you use the last formula I put here and input Q to find W.
