Question
A freezer sustains a cold environment of -32°C and exhausts its heat at 39°C. Assume a Carnot cycle.
If the freezer removes 325 kJ of heat from the cold environment, how much heat does it exhaust?
Express your answer to the nearest joule.
Expert Solution
Step 1
The given data
The initial temperature T1 = -32C = -32+273 = 241 K
The final temperature T2 = 39C = 39+273 = 312K
The given heat energy Q1 = 325 kJ
