Why does water freeze from top to bottom?

Does a waterfall freeze from top or bottom?

Does a waterfall freeze from the top or bottom? Marten said it freezes at both ends and in between. The frazil ice attaches to cold rocks or cliff hangs depending on the falls’ terrain. It then becomes an anchor for which more ice can form as water flows over.

What happens to the water when it freezes?

During freezing, water molecules lose energy and do not vibrate or move around as vigorously. This allows more stable hydrogen-bonds to form between water molecules, as there is less energy to break the bonds. Thus water expands as it freezes, and ice floats atop water.

Why does the bottom of my fridge keep freezing?

This may seem like a dumb solution, but it’s actually valid. GE explains how if the food at the bottom of your fridge keeps freezing, it could simply be because your fridge isn’t fully packed. Refrigerators need to be well-stocked to absorb all of the cold air being vented into the cavity.

Can a leak in the freezer cause a refrigerator to freeze?

Leaky Door Seals The seals around your refrigerator and freezer doors help keep cold air in. If one or both of these seals are leaking, your refrigerator will work harder to maintain a constant temperature. Unfortunately, this can lead to a refrigerator that’s too cold – and frozen food.
