Choose the expressions that correctly describe total in this situation. a. The total number of microstates in the right half of the box. b. The total number of microstates in the left half of the box. c. A function of the volume V1 in the left half of the box. d. A function of the total volume V of the box. e. The total number of microstates available to the system. f. The total number of microstates in the system and surroundings
