An ideally efficient air conditioner keeps the room air at 290 K when the outdoor air is at 305 K. How much work does it consume when delivering 900 J of heat outside?
Answers: 3
where in this case 
is 290 K and 
is 305 hence

If the temperature were raised very high, classically what would we expect the heat capacity per object to be for this one-dimensional system? give a numerical value. chigh t = __ j/k/object (one reason for the discrepancy is that the high-temperature limit assumes that the number of oscillators is large (n > > 1), which is not the case in this tiny system.)
