Two blocks with different temperatures had entropies of 10 j/k and 30 j/k before they were brought in contact. what can you say about the entropy of the combined system after the two came in contact with each other? a.ssystem > 40 j/kb.ssystem = 20 j/k c.ssystem < 20 j/kd.ssystem > 20 j/ke.ssystem = 40 j/kf.ssystem < 40 j/k

a. Ssystem  > 40 J/K

Explanation:

Given that

The entropy of first block = 10 J/K

The entropy of second block = 30 J/K

When two bodies come into contact with each other, the entropy of the combined system will increase and the entropy sum remains unchanged: According to the Second law of thermodynamics.The entropy of the system will be greater than 40  J/K.

Therefore the answer is a.

Ssystem  > 40 J/K
