The statement that best explains why the room starts to feel cooler when a teacher opens a window on a cold day is:

**A. Air moves from the areas of higher temperature to areas of lower temperature.**

This is because warm air inside the room moves out to the colder outside air, and colder air from outside comes in, resulting in a cooler feeling in the room.
