Cooler Beer
If I have a beer in the fridge, will it be cooler if I had 10 beers?
Does the amount of things influence the cold fridge objects? For example, there is a limited amount of "coolness" of the refrigerator can exercise, or all get equally cold, no matter how much things that are there? O is a third possibility, objects do not have more in the refrigerator to keep it cooler because the objects themselves to stay cool and help cool each other and new objects?
If you have a beer in the fridge, they cool faster than if you have 10. There is no such thing as "cool" and is not an amount. What you are dealing with is how quickly the fridge can circulate cold air to dissipate heat in the beer. If you have only one, does not radiate much heat, so it cools faster. (Remember that beer is mostly water, and water has the highest known specific heat of any substance, which mean it takes a lot of energy to raise its temperature. Similarly, you have to take a lot of energy to be cold.) Once cold objects more in the fridge will help things stay cold if the fridge goes off (again specific heat – the colder it gets the first set, and take a lot of heat for heating), and have the things that you've already cold in helping something that is new and hot to cool faster, because Cold things leech heat, making hot stuff cold. Over time, everything in the refrigerator will be more or less the same temperature, without prejudice or the cooler air circulates, how many times you open the door and so on. This is called entropy, and it happens all the time (All the beer in the bottle is the same temperature, all the beer in the fridge are the same, and so on).
