What do refrigerators use to absorb heat and lower the temperature of the food inside?

FREON.
Freon is now illegal because it damages the Earth's ozone layer. The replacement refrigerant is the inert gas tetrafluoroethane commonly called R134a. Also note that the refrigerator does not"absorb" the heat. It is transferred from inside the compartment to outside the compartment. It does this by the use of two heat exchangers. One transfers the heat from the inside to the refrigerant and the second transfers the heat from the refrigerant to the outside.

What is the seemingly lower temperature due to excessive breeze?
The lower temperature is called wind chill
Does a lower Celsius number mean colder?
Yes, it does. A lower number means a lower temperature.
When placed into water will ammonium chloride decrease the temperature of the water?
The dissolution of ammonium chloride, like ammonium nitrate, is an endothermic process, meaning that it will absorb heat. The amount of heat absorbed per mole of ammonium chloride (53.49 g) is 14.7 kJ, enough to lower the temperature of one kilogram of water by 3.5 K.
What is temperature range for lower mantle?
The temperature ranges from 932 to 1,652-degrees F, at the top, where it meets the crust, to 7,230-degrees F at the lower mantle. Temperature and pressure increase with depth.
What happens when matter at a higher temperature touches matter at a lower temperature?
The colder matter absorbs the heat (thermal energy) from the hotter matter. Heat continues to "flow" until all of the matters is at about the same temperature. This is a fundamental law of thermodynamics; heat travels from where it's hotter to where it's colder.
Can an object absorb heat?
Yes, provided its own temperature is lower than that of the incident rays.
What are two compound refrigerants?
Refrigerants are substances which are used in refrigerators and they are generally gases. They are periodically compressed and allowed to expand adiabatically in order to bring the temperature lower and lower. This is how the temperature inside a refrigerator gets lower and lower. CFC (Chlorofluoro Carbon) and Methane (CH4) are such two compound refrigerants. Now a days due to environmental issues the practice of using these gases as refrigerants is discouraged. They are found to be potent global warming gases.
Why the temperature of the water increases from trial one to trial three?
During the time water absorb heat from the atmosphere if the initial temperature was lower.
Why is the temperature needed to freeze ocean water lower than the temperature needed to freeze the surface of a fresh lake?
The ocean is larger than a lake. Therefore, being larger it can absorb more heat. That is why a lower temperature is needed to freeze it.
Why is the temperature needed to freeze ocean water lower than the temperature to freeze the surface of a fresh water lake?
The ocean is larger than a lake. Therefore, being larger it can absorb more heat. That is why a lower temperature is needed to freeze it.
How do microprocessors work in refrigerators?
== == It controls the temperature inside the fridge, so you don't have to
Why is the temperature needed to freeze ocean water lower than the temperature needed to freeze a surface of a fresh water lake?
The ocean is larger than a lake. Therefore, being larger it can absorb more heat. That is why a lower temperature is needed to freeze it.
Why do foods kept in a refrigerator is lasts longer than food stored in cabinet . which involving chemistry?
refrigerators have a much lower temperature than that in a cabinet. microbes,for growth often needs a suitable temperature that is at around 25-30C. hence, lower temperature slows or even sometimes stops the growth of microbes on food.
Does water inside a vacuum boil at a higher or lower temperature than it does under normal pressures?
It boils at a lower temperature because of the less energy needed.
If the coolant in an air conditioner has a lower temperature the the air in a building then?
Heat will flow from the coolant to the air The coolant will absorb the heat from the building.
If the coolant in an air conditioner has a lower temperature than the air in a building then?
Heat will flow from the coolant to the air The coolant will absorb the heat from the building.
If the coolant in the an air conditioner has a lower temperature than air in building then?
Heat will flow from the coolant to the air The coolant will absorb the heat from the building.
