Homework Answers
When it comes to bananas, people seem to have various notions on the correct amount of ripeness.Some prefer them light yellow with a greenish stem where the fruit is just barely ripe, and that’s an idea of a perfect banana. Next is the yellow stage, which is mainly considered as the peak of perfection, after that is yellow with brown spots, and lastly is brown on the verge of black.There is a fine line between not ripe enough to overripe. Bananas are pretty easy to store. Simply keep them on the counter at room temperature. Depending on what stage of the ripening process the fruit’s at, they should last this way for 2-6 days. Again, it will greatly depend on how ripe you like them, and how ripe they were when you purchased them.

A Carnot refrigerator (the reverse of a Carnot engine) absorbs heat from the freezer compartment at a temperature of -2degreeC and exhausts it into the room at 25degreeC. How much work must be done by the refrigerator to change 0.30 kg of water at 25degreeC into ice at -2degreeC? If the compressor output is 210 W, what minimum time is needed to accomplish this?
