Question

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

In: Chemistry

Answer 1

The air inside the fridge cools the container, the container cools the air inside the container, the air inside the container cools the food.

All those interfaces slow down the process so your food will cool down much slower than if it was directly in the fridge on an open plate but the cold will get to it eventually.
