How does convection happen in a refrigerator?
In a refrigerator, convection occurs when the cool air sinks down as it is denser, while the warmer air rises up. This creates a circulation of air inside the refrigerator that helps maintain a consistent temperature and cools the items inside. This process helps to distribute the cold air evenly and keep the refrigerator contents fresh.
How those evaporator works in a refrigerator system?
An evaporator in a refrigerator system works by absorbing heat from inside the refrigerator, causing the refrigerant inside the coils to evaporate into a gas. This process cools the interior of the refrigerator. The evaporator coils are where the evaporation of the refrigerant occurs, and the circulation of air inside the refrigerator helps to transfer the heat from the interior to the coils.
What would you expect to happen to a balloon filled with air if it was out into a refrigerator?
The balloon would shrink in size as the air inside cools and contracts. This is because gases, like the air in the balloon, contract when they are cooled and expand when they are warmed.
Why is the freezer at the top of a refrigerator instead of at the bottom?
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.
How does refrigerant work in the cooling process of a refrigerator or air conditioning system?
Refrigerant works by absorbing heat from inside the refrigerator or air conditioning system and carrying it outside. As the refrigerant evaporates, it cools the air inside the system. The refrigerant then condenses back into a liquid, releasing the heat outside, and the cycle repeats to keep the space cool.
What cools the air inside a household refrigerator?
Absorption of the heat from the air due to evaporation of the liquid refrigerant.
How is the air cooled in a household refrigerator?
It goes through the pipes
Why soda can is cold when taken out of refrigerator?
When the soda can is placed in the refrigerator, it absorbs the cold temperature of the surrounding air and cools down. This causes the can to feel cold to the touch when you take it out of the refrigerator.

Why should a refrigerator not be overpacked?
A fridge operate more efficiently when the cold air that cools the food can move around
What is the difference between a refrigerator and a heat pump?
A refrigerator takes heat out of a small compartment by expanding a gas and utilising the laws of thermodynamics; a heat pump pumps warm air, heated by the sun, from a roof cavity into rooms in a houseto warm them and pumping the cold air into the roof to be heated.
What would happen to a blown up balloon if it is placed in a refrigerator?
When the air inside a balloon cools, it will also contract, therefore the balloon will partially deflate.

What is the temperature of the air in a refrigerator?
The temperature of air in a refrigerator is about 3.3 Degrees Celsius
