Natural disasters can cause both immediate and long-term issues. For example, flooding is an immediate threat with dangerous high waters, and it can also cause an area to lose electricity for extended periods of time. To combat this, engineers have designed boxes that can keep food cool when there is no electricity for refrigeration. How should engineers design the boxes to be sure that the food within each box is not spoiled due to thermal energy transfer? A. The boxes must maximize thermal energy transfer to prevent thermal energy from transferring out of the boxes. B. The boxes must minimize thermal energy transfer to prevent thermal energy from transferring into the boxes. C. The boxes must minimize thermal energy transfer to prevent thermal energy from transferring out of the boxes. D. The boxes must maximize thermal energy transfer to prevent thermal energy from transferring into the boxes.
