nopes.. surprisingly the room temp.will increase
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.
Earth would be considerably colder.... actually a lot colder. I'm not sure how much colder but you can try to figure that out.
Pluto is the coldest planet not neptune is not the coldest planet in are solar 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.
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.

The laws of nature would make this impossible, some energy always escapes.
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.
A closed system would be full of freon without any leaks and a opened system would have no freon or has leaks...........
As it gets colder the air molecules move closer together and the balloon deflates.
BOIL IT! or buy a filter system for your refrigerator
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).
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.
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..
A closed system does not let any matter enter or exit, and no energy enters or exits the system.
The volume shrinks.
In reality closed systems do not exist. In the theoretical case of a closed system the total energy of the system would stay the same (matter and particles are considered energy to). More important: the energy level throughout the whole system will eventually be evenly spread and uniform (entropy), therefore no energy differential is left to perform work.
