Question: Two objects , B1 (T = 40 ) and B2 ( T = 18 , experienced entropy changes of 6.4 x 10^4 J/K and 2.8

Two objects , B1 (T = 40℃ ) and B2 ( T = 18℃ , experienced entropy changes of 6.4 x 10^4
J/K and 2.8 x 10^4 J/K, respectively, after they had been placed in direct contact with each other. B1 lost 2.0 x 10^7 J of heat. How much heat was lost by B2 ? What was the entropy change in the universe after the process?
