Modern electric fridges are cooled by the evaporation of a low boiling point liquid. The resulting gas is then compressed and cooled (in the fins at the back of the fridge) to condense it back to a liquid. It then goes through the cycle again and again. See link to animated drawing for details. The liquid/gas used in fridges manufactured before the mid 1980s was genereally a CFC (Chloroflourocarbon) but these were banned under the Montreal treaty in 1989 due to their damaging effect on the ozone layer. Currently they have been largely replaced by HCFC in modern fridges but HCFCs although not harmful to the ozone layer are powerful global warming gasses. Their use is due to be banned by 2030 if not sooner.
D - Absorption of the heat from the air due to evaporation of the liquid refrigerant.
What else can I help you with?
Which of the following cools the air in a household refrigerator?
The compressor is the part of a household refrigerator that cools the air. The function is absorption but the compressor creates the absorption.
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.
Which of the following cools the air in a household refrigerator?
The compressor is the part of a household refrigerator that cools the air. The function is absorption but the compressor creates the absorption.
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.

This creates a circulation of air inside the refrigerator that helps maintain a consistent temperature and cools the items inside.

What does refrigerator?
It cools food
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 does the compressor of a refrigerator do?
It makes noise and cools everything.
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.
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.
