2. Two objects , B1 (T 40C) and B2 (T= 18C, experienced

2. Two objects , B1 (T 40C) and B2 (T= 18C, experienced entropy changes of 6.4 x 10 J/K and 2.8 x 10 J/K, respectively, after they had been placed in direct contact with each other. Bi lost 2.0 x 10' J of heat. How much heat was lost by B2 ? What was the entropy change in the universe after the process ?
