Question
Heat transfer and entropy1. During a process with duration of one minute, consider QH and QL, the heat transfers to the high-temperature and low-temperature cubes, respectively.
a) Is QH, the heat transfer to the high-temperature cube, positive, negative, or zero?
b) Is QL, the heat transfer to the low-temperature cube, positive, negative, or zero?
c) Compare the magnitudes (absolute values) of QH and QL; is one larger than the other? If so, which one?
d) Is the sum [QH + QL] positive, negative, or zero?
e) For this process, is energy a conserved quantity? Explain.
Explanation / Answer
QH NEGTIV QL POSTIV QL IS LARGER SUM IS NEGTIV NO. SOME ENERGY IS LOST TO SURROUNDINGS
