The refrigerator is cold at the bottom and warm at the top because warm air rises. Cold air is heavier than warm air and settles toward the bottom of the appliance.
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.
The cooling unit in the refrigerator is typically located at the top. As a result, cold air is generated at the top and then circulates down to the bottom. This can lead to the bottom being warmer as the cool air sinks and the warm air rises. Regularly cleaning the coils at the back can help with air circulation and temperature regulation.
It is colder at the top of a refrigerator because cold air sinks, causing the lower portion to be slightly warmer.
Having the freezer at the top of the refrigerator allows cold air, which is denser and tends to sink, to flow into the refrigerator compartment more easily. This design also makes it more convenient to access frequently used items in the refrigerator.
Most units have a fan to circulate cold air and maintain the compartment at a uniform temperature. Without this, the cold air will settle at the bottom, and the thermostat will not get an accurate reading, leading to over-short or over-long cooling cycles. The fan could be broken, or part of the system that controls the fan (like the motherboard or a relay) could be broken. Additionally, the fan could have failed and taken out part of the electronics.

Bottom so less cold air escapes and most people use refrigerator more than freezer which will require less bending over.
Warm gases and warm fluids rise to the top. Same principle that makes hot air balloons fly.
The cooling fan inside the computer draws in cold air from the bottom of the case - and expels warm air from the top.
Because warm air is lighter then cold air. So warm air will raise (to the top of the room) and cold air will stay down. When the warm air is cooling down it lowers and when cold air is heated/heating up it raise.
Cold will sink to the bottom. Hot water will rise to the top.
its not always at the bottom its just the way yours is made some other people have asked why is it at the TOP of the refrigerator so my answer is that its just a selective spot depending on what fridge you have. In fact, the majority of refrigerator/freezer combinations have the freezer on top. As mentioned in other posts, hot air rises and cold air sinks, so freezer-on-top models can transfer cold air to the refrigerator without using as much electricity as other models, making freezer-on-top models the most energy efficient refrigerators (generally speaking) that you can buy.

Cold air falls and warm air rises
