Problem
1. A rock bed consists of 6000 kg granite and is at 70oC. A small house with a lumped mass of 12 000 kg wood and 1000 kg iron is at 15oC. They are now brought to a uniform final temperature by circulating water between the rock bed and the house. Find the final temperature and the irreversibility of the process, assuming an ambient of 15oC.
2. A computer CPU chip consists of 50 g silicon, 20 g copper, and 50 g polyvinyl chloride (plastic). It now heats from ambient, 25oC, to 70?C in an adiabatic process as the computer is turned on. Find the amount of irreversibility.
The response should include a reference list. Double-space, using Times New Roman 12 pnt font, one-inch margins, and APA style of writing and citations.
