A teacher opens a window on a cold day. Which statement explains why the room starts to feel cooler? (1 point)

Cold air is moving into the room from outside.
Air moves from the areas of higher temperature to areas of lower temperature.
The density of the air is lower on the inside than on the outside.
The kinetic energy of the air molecules outside is higher than the kinetic energy of the air molecules inside.

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

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

This statement effectively describes the principle of heat transfer, where warmer air inside the room will naturally move towards the colder air outside, resulting in a cooler room.
