In an effort to save energy and, thus, money, many people keep their electric freezers halfempty at all times, using them to store prefrozen foods bought at a store and nothing else. Yet freezers that are half-empty usually consume more energy than they would if they were kept fully stocked.
Which of the following, if true, contributes most to an explanation for the apparent discrepancy described above?
  • a)
    A person who normally maintains a halfempty freezer would save a considerable amount of money by using a freezer that is half as large.
  • b)
    An electric freezer can operate efficiently only if chilled air is free to circulate within the freezing compartment.
  • c)
    A given volume of air in a freezer requires much more energy to be maintained at a temperature below freezing than does an identical volume of frozen food.
  • d)
    The door of a full freezer is likely to be opened more often, and for a longer period of time, than is the door of a halfempty freezer.
  • e)
    On average, it takes less energy to keep food frozen than it does to get it from room temperature to a frozen state.
Correct answer is option 'C'. Can you explain this answer?

Let's examine each answer choice and determine which one provides the best explanation for the apparent discrepancy described in the question.
(A) A person who normally maintains a half-empty freezer would save a considerable amount of money by using a freezer that is half as large.
This answer choice suggests that using a smaller freezer would save money, but it does not explain why a half-empty freezer would consume more energy than a fully stocked one. Therefore, it does not contribute to explaining the discrepancy.
(B) An electric freezer can operate efficiently only if chilled air is free to circulate within the freezing compartment.
This answer choice highlights the importance of proper air circulation within the freezer. However, it does not specifically address why a half-empty freezer would consume more energy. It provides a general condition for efficient operation but does not directly explain the discrepancy.
(C) A given volume of air in a freezer requires much more energy to be maintained at a temperature below freezing than does an identical volume of frozen food.
This answer choice is the most plausible explanation for the discrepancy. It suggests that maintaining a volume of air at a temperature below freezing requires more energy compared to maintaining the same volume of frozen food at the same temperature. In a half-empty freezer, there is more air than frozen food, which leads to increased energy consumption.
(D) The door of a full freezer is likely to be opened more often, and for a longer period of time, than is the door of a half-empty freezer.
This answer choice suggests that a full freezer may be accessed more frequently, potentially leading to increased energy consumption. However, it does not explain why a half-empty freezer, in general, consumes more energy. This explanation would depend on individual usage patterns and does not provide a consistent reason for the discrepancy.
(E) On average, it takes less energy to keep food frozen than it does to get it from room temperature to a frozen state.
This answer choice compares the energy required to maintain frozen food versus the energy required to freeze it initially. However, it does not address the discrepancy between a half-empty freezer and a fully stocked one. It provides information about energy usage during the freezing process but does not explain the energy consumption difference between the two scenarios.
In conclusion, option (C) provides the most reasonable explanation for the apparent discrepancy described in the question.
