Suppose we have two identical boxes of matter, A and B, that are in thermal contact but cannot exchange materials. They come to thermal equilibrium. System 1 consists of box A alone, while system 2 consists of both boxes A and B. What can you say about the entropy of the two systems? Choose all correct answers.

a. The entropy of system 2 is twice as high as that of system 1. b. The entropy of system 2 is a lot more than twice as high compared to system 1. c. The number of microstates of system 2 is twice as high as those of system 1. d. The number of microstates of system 2 is a lot more than twice as high as those of system 1. e. You cant tell anything about the comparative entropy of the two systems without more information.
