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 else can I help you with?
Can water absorb more heat than land?
Water has a higher heat capacity than land, meaning it can absorb more heat for a given temperature change. However, land heats up and cools down more quickly than water due to its lower heat capacity, which can result in more extreme temperature fluctuations on land compared to water.
How can a researcher ensure that water is being used for an experiment that will vaporize at a point lower then normal temperature?
The researcher can lower the pressure inside the experimental setup to decrease the boiling point of water, allowing it to vaporize at a lower temperature. This can be achieved using a vacuum pump to create a vacuum environment. It's also important to monitor the temperature and pressure conditions during the experiment to ensure accurate results.
What is the lower layer temperature?
The lower layer temperature typically refers to the temperature of the lower atmosphere, which can vary depending on location, time of day, and weather conditions. It is important for understanding weather patterns and climate dynamics.
Why is bulb temperature is lower than the dry?
Bulb temperature is typically lower than dry temperature because the bulb thermometer measures the temperature of the air without factoring in the effects of evaporation. The dry bulb temperature, on the other hand, accounts for the cooling effect of evaporation, giving a lower reading than the bulb temperature.
What the temperature in Celsius of the earth's lower mantle?
The temperature in the Earth's lower mantle is estimated to be between 1,600 and 2,200 degrees Celsius.
How do heat engines use thermal energy and how do refrigerators keep things cold?
Heat engines use thermal energy to generate mechanical work by transferring heat from a high-temperature reservoir to a low-temperature reservoir. Refrigerators keep things cold by using a refrigerant to absorb heat from the inside of the unit and release it outside, thereby maintaining a lower temperature inside.
Can an object absorb heat?
Yes, provided its own temperature is lower than that of the incident rays.
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.
Does fertilizer in water lower the temperature?
No, fertilizer in water does not lower the temperature. The presence of fertilizer can actually increase water temperature indirectly by promoting the growth of algae and other plants, which can absorb sunlight and heat up the water.
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 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 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.
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.
What is a material used to cool an area to a temperature lower than the temperature of the environment called?
A material used to cool an area to a temperature lower than the temperature of the environment is called a refrigerant. Refrigerants absorb heat from the surroundings and release it elsewhere, enabling the cooling process to take place.
How does the refrigeration cycle in a heat pump work to transfer heat from a lower temperature source to a higher temperature sink?
The refrigeration cycle in a heat pump works by using a refrigerant to absorb heat from a lower temperature source, such as the air outside, and then transferring that heat to a higher temperature sink, such as the inside of a building. This process is achieved through the use of a compressor, condenser, expansion valve, and evaporator, which work together to circulate the refrigerant and facilitate the transfer of heat.
An object that is warmer than its surroundings will absorb heat?
An object that is warmer than its surroundings will actually transfer heat to its surroundings, not absorb it. Heat transfer occurs from regions of higher temperature to regions of lower temperature in an effort to achieve thermal equilibrium.
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.
