1. A pan in an auto shop contains 5 L of engine oil at 20?C, 100 kPa. Now 3 L of oil at 100?C is mixed into the pan. Neglect any work term and find the final temperature and the entropy change.

2. A computer CPU chip consists of 50 g silicon, 20 g copper, and 50 g polyvinyl chloride (plastic). It heats from 15?C to 75?C as the computer is turned on. How much did the entropy increase?
