Because colder air is denser than warm air and it tends to sink.

The bottom of the fridge is typically colder because the cooling unit (evaporator coil) is often located at the back of the fridge near the bottom. As the cold air is generated, it tends to sink to the lowest point in the fridge, which is why the bottom shelf or drawer tends to be the coldest.

What type of energy does the fridge give off?

A fridge gives off heat energy as it extracts heat from inside and releases it outside to maintain a cool temperature inside. This heat is dissipated by the fridge's coils, usually located at the back or bottom of the appliance.


Would butter cheese or fish be the coldest in a fridge?

Assuming they've all been in there long enough to equilibrate, and assuming you haven't put them in some "special" location that's colder or warmer than average (the shelves in the door, for example, are often slightly warmer than the main shelves), they will all be the same temperature.


If you leave the fridge in your kitchen open for 10 minutes after an hour is the room warmer or colder than it would have been had you not?

If you leave the fridge open for 10 minutes in the kitchen, the room will be slightly warmer than it would have been if the fridge had not been open. This is because the warm air from the room enters the fridge, causing the fridge to work harder to cool down again and in turn releasing some heat back into the room.


Why is a freezer compartment at the top of a refrigerator?

The cooling element in freezers is at the top in order to keep it its coolest. This is because in a freezer or fridge the heat travels using thermal convection. In your kettle you have a the heating element at the bottom so the water particles are less dense and rise upwards beofore cooling at the top and becoming colder denser particles that then replace thehot particles at the bottom. This cycle carries on....however in a fridge or freezer you want the particles to be colder and denser so the cooling element is at the top so it allows the particles rise then to cool faster at the top. Its basically the reverse of what you have in your kettle, that allows you to boil your water!


Why is the top of your refrigerator cold but not the bottom part?

The top of the refrigerator is cold because that's where the cooling unit is located, usually at the back. The cold air sinks, so it tends to stay at the bottom of the fridge where it keeps the food cool.

Usually the higher number means coldest. Think of it as "Fridge Power". It's silly but it makes sense. The purpose of the Fridge is to keep things cold. So, if you want it colder, you neeed more power. Turn it up and get frosty.

About Refrigerators with Bottom Freezers?

Though refrigerators with bottom freezers can be convenient, as the freezer allows more of the inside of the fridge to be at eye level, they're more expensive and a bottom freezer tends to hold less. Other than that, their maintenance is pretty much the same as top freezer refrigerators. Spills inside the fridge or freezer should be wiped up at once. An open box of baking soda should be put in both the fridge and freezer to absorb odors. It should be replaced every three months. Foods in the freezers should be stored in freezer bags, which should be dated. The coldest parts of the freezer are against the walls or the bottom of the compartment and items should have enough space between them for air to circulate.

What would cause a fridge to have water in the bottom that freezes?

Well, either your temperatures are inconsistent, often melting things and refreezing them; the other possibility is that if you have a fridge with a conjoined water dispenser, then that is leaking and pooling at the bottom to freeze.
