Imagine a closed physical system - an insulated glass box on a table. In the box are two cubes of pure gold. Instruments indicate that Block A is 1 kg and Block B is 1.5 kg. Block A has a temperature of 26°C and Block B has a temperature of 32°C. The two blocks are pressed against each other.
Which describes the system when it reaches thermal equilibrium?

a. The KE of molecules in every object of this system will be equal. Therefore, the temperature of the air inside the box and both blocks will be the same.
b. The KE of molecules in the blocks will be the same, but different from the air molecules. Therefore, the temperature of the air inside the box is different, but both blocks will have the same temperature.
c. The KE of molecules in every object of this system will be different based on the molecule type. However, the temperature of the air inside the box and both blocks will be the same.
