Two blocks are placed in contact with one another. The one on the left has a temperature of 150 K, and the one on the right has a tempera- ture of 275 K. Left alone, what will happen to the temperatures of the objects? A The blocks will both reach an equilibrium temperature between 150 K and 275 K. B Each block will take on the other block's temperature, with 275 K on the left and 150 K on the right. C Both blocks will become hotter until their temperatures reach 425 K. Both blocks will lose heat until they reach a temperature of 125 K.
