Which part of a refrigerator determines whether it is an open or closed system?
The part of a refrigerator that determines whether it is an open or closed system is the refrigeration cycle, particularly the refrigerant flow. In a closed system, the refrigerant is contained within a closed loop of coils, absorbing heat from the interior and releasing it outside without any mass exchange with the environment. In contrast, an open system would involve the exchange of mass, where refrigerant could enter or leave the system. Most traditional refrigerators operate as closed systems.
What is colder a can of coke or a glass of coke?
I would say the glass of coke (served with ice-cubes in it) is colder than the can. The melting ice-cubes in the glass of coke hold it at constant freezing/melting temperature (32F), the can of coke comes out of the refrigerator at the same temperature as the refrigerator (~35F) and warms from there.
How many kilowatt hours does a party refrigerator use in a day?
The energy consumption of a party refrigerator can vary, but on average, a party refrigerator might use around 1-2 kWh per day. This can depend on factors such as the size of the refrigerator, its energy efficiency rating, and how often it is opened and closed during the day.
Is the water cycle an open or closed system?
Closed. Except for the rare case of humans launching objects into space and meteorites striking the planet (which represent an incredibly miniscule fraction of the total carbon), the amount of carbon in the system remains at a constant mass.
What is open and closed system?
Open systems refer to systems that interact with other systems or the outside environment, whereas closed systems refer to systems having relatively little interaction with other systems or the outside environment.
How would a refrigerator be measured in metric weight?
A refrigerator would typically be measured in kilograms (kg) in terms of weight in the metric system.
Why refrigerator is called closed loop control system?
A closed loop system is one where the ouput of the system is at least part of the input. In a refrigerator, the output of the cooling system (the cold air inside the refrigerator) is measured, and is fed back into the system to determine whether the system needs to continue cooling. An example of a fridge that was an open loop system would be one that turns on and cools for 1 hour every 6 hours, regardless of internal temperature.
To purify water you would?
BOIL IT! or buy a filter system for your refrigerator
What is the difference between opened and closed system of air conditioning?
A closed system would be full of freon without any leaks and a opened system would have no freon or has leaks...........
Can a refrigerator get colder by installing a lower temp thermostat?
In basic theory yes it would get colder by installing a lower temp thermostat. However the common household refrigerator was not designed for that application,..most household Units set at the lowest temp can cool down to about 35*F in the refrigerator section,and 20-28*F in the freezer section... putting in a lower temp thermostat may cause the unit to run constantly as it tries to achieve the lower temp settings and If your unit runs constantly your electric bill will skyrocket and I would estimate that within 3-7 days of constant running you would either burn out a thermal overload or the compressor unit...

Will your refrigerator keep food and drinks cold if you disconnect it from the wall outlet?
A working refrigerator with the doors closed can keep food cold just a couple hours. You would then need to plug the unit back in.
How do you make water cold?
An easy way to make water cold is to put it in the refrigerator. If this is not possible, adding colder water would make water colder. Actually, adding ice would make this process faster, as it is colder than cold water. And dry ice would make it cold even faster than ice (but dry ice is dangerous- be careful).
Can you unplug and replug in a refrigerator?
yes, after 4 hours past since you unplugged it, you can replug it! 4 hours would be good because of how a refrigerator system works..
What type of system would allow light to enter and exit but would keep any additional atoms out?
A closed system does not let any matter enter or exit, and no energy enters or exits the system.
A well-defined group of objects that transfer energy to one another?
A system is a well-defined group of objects that transfer energy to one another. This transfer can take place as a result of mechanical work, heat, or electromagnetic radiation within the system. Systems can be open, closed, or isolated depending on the exchange of matter and energy with their surroundings.
Which system would you use to demonstrate conservation of mass?
A closed system would be used to demonstrate the conservation of mass. In a closed system, no mass enters or exits the system, allowing for the observation of mass being conserved through chemical reactions or physical changes.
