How does energy flow when a refrigerator door is accidentally left open? In other words, does the cold air from the fridge flow out or does the heat from the room flow inside the fridge?

Explanation:

Energy as heat flows from a body of higher temperature to a body of lower temperature.

In this question, inside the refrigerator represents the lower temperature. The room temperature represents the body of higher temperature.

Hence;

The heat would flow from inside room to inside the fridge.

the old alchemists made significant contributions to science even though there starting premises were off a bit. their conclusions after failure would steer them into better directions for investigation. science is no more than close observation and the initial mistakes result in rethinking and retrying experiments.

"hydrogen bonding is the attraction of h atoms in the water molecule (slight + charge) to o atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. but it is still strong enough to the water molecules "stick" together."
