If our immune system were that weak as to be affected by a few hours in cold temperature we would really be in trouble. viruses cause colds, usually the rhinovirus. The only way that freezer would give you a cold is if you were working with someone who had a cold in the freezer either at the same time or a day or two before. Wash your hands frequently and don't touch your nose, mouth or eyes.
See the related questions about common colds not being caused by being cold.
Working in a freezer does indeed have effects on a human. A human might for example freeze to death if they do not dress properly.
Working in a freezer does not cause arthritis. However, if someone is already suffering from arthritis, the cold will increase the intensity of it.
The life of the freezer depends on the conditions in which it is housed. If the garage is humid, hot or conversely very cold, then your freezer is better off inside.
something that is cold and solid like ice but that stuff does not melt
The inside of a freezer is very hard to calculate! Although, I have calculated that it is about 15 to 31 degrees Celsius.
It might be out of freon.
You need something really cold. You or anything from inside your house will be too warm and the snowflake will melt as soon as it touches. If the weather outside is cold enough, you can leave something, like a spoon, outside until it cools off. Then you can use it to catch a snowflake. If the weather is too warm (the snow is not sticking to the ground, but melting), put the spoon in your freezer for a hour or so.
The air particles inside are less active, and tend to clump together because of the cold
My refrigerator is not running cold nor is the freezer. It is blowing warm air.
cold, very cold.
Any freezer needs to be kept closed as much as possible if you wish for it to remain cold. However a chest freezer will not warm up as fast as an upright freezer. This is because the cold air in the freezer is heavier than the air outside of the freezer. When you open an upright freezer the cold air "falls" out, this can't happen with a chest freezer.
hot water in a freezer will get hotter depending if the freezer is turned on.
Strangely enough fridges and feezers actually need to have stuff inside them to work properly. A fridge or a freezer will work best when they are about 60-75% full. If they are too empty or too full then they won't be as cold.
