To make your refrigerator colder, you can adjust the temperature setting to a lower setting. This will cause the refrigerator to work harder to maintain a lower temperature, making it colder. Additionally, make sure the vents and coils are clean and not blocked to allow for proper air circulation.
Should be a setting on the control panel or inside the refrigerator itself.
It is colder at the top of a refrigerator because cold air sinks, causing the lower portion to be slightly warmer.
On a refrigerator "5" is usually a colder temperature setting than "1". On heaters the opposite is true: 1 is usually the lowest temperature setting, and numbers greater than 1 are for higher temperatures.
Refrigerator improves its design and capacity year after year.
Because the temperature inside the refrigerator is colder than the temperature outside

Freezer is colder
No, placing an open refrigerator in a closed system would not make it get colder. The cooling effect of a refrigerator is achieved by removing heat from the inside and releasing it outside. In a closed system, the removed heat would simply accumulate, leading to the refrigerator eventually reaching thermal equilibrium with its surroundings.
A refrigerator gets colder when the number is turned higher.
Yes, assuming that your refrigerator is set at 40°F. or colder.

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).
