Frecze-drying is a process used to preserve food. If strawberries are to be freeze-dried, then they would be frozen to -80 °C and subjected to a vacuum of 0.001 torr. As the water is removed, it is frozen to a cold surface in the freeze-drier. If 150 mL of water has to be removed from a batch of strawberries, how much energy would be required? What changes of state are taking place? At any given time, how much water is in the atmosphere if the volume of the freeze-drier is 5 liters? If it takes one hour to remove one mL of water, how long will it take to freeze-dry the strawberries?
