If I put an air-tight container into the fridge, how do the contents still get cold?

In: Chemistry

Answer 1

When an object is cold, that just means it has less heat energy. When you put a container in the fridge, the contents get cold because the heat energy that is inside the contents of the container will transfer to the container itself, and then from the container to the cold air in the fridge.

Heat always travels warm -> cold, and it doesn’t care whether there’s physical barriers in the way, because it travels *in* the physical objects
