The surrounding air works with the hot food, cooling it off. This is because heat naturally wants to escape and cool off. Once it reaches air temperature, it cannot physcially cool off any more, though.

depends on the "ingredients" a hot potato takes a lot longer than a noodle to cool down.
Yes. The meringue has to set.
That will depend upon the specific bacterium. Some will grow rapidly at room temperature, others will not.
no this depends on air flow and other factors within the room, but in a controlled environment it does yes.
Food cooling is storaging your vegetables, fruits and frozen food in a cold temperature room.
leave it to cool in a cool room to about room temperature and then refridgerate.
Yes they are, or at least room temperature.

It is not safe to consume chicken which has been allowed to reach room temperature and then refrozen. This is often the cause of food poisoning. Once a food has reached room temperature it should be thoroughly cooked and then eaten or allowed to cool and then stored in a refridgerator.
At room temperature sodium chloride is a solid.
You should allow food to cool at room temperature. Putting the food in the fridge or freezer before its temperature lowers to room temperature could result in the food being unsafe to eat.
The countertop is at room temperature, which is lower than body temperature, so it feels cool to the touch.
No. Serve it at cool room temperature.
The rule for cooling food is that you want to get it from 135 degrees (F) to 70 degrees in the first 2 hours, and then from 70 to 41 degrees over the next 4 hours. So, yes, you can initially cool your food at room temperature, just make sure that it can make it to room temperature within that first couple of hours. The important thing is that you take measures to help your food cool as quickly as possible. For example, for dense things like mashed potatoes, you should spread them out in a pan or on a plate to have a larger cooling surface. Cool in metal or glass when possible, they will allow for faster cooling than plastic, which is an insulator. For larger batches of things like soups and sauces, you probably shouldn't cool at room temperature. I find it's fastest to cool it directly in the pot, in the sink in an ice bath. Give it a stir every now and then to speed up the process.
Room temperature is 20 - 25 degrees Celsius (68 - 77 degrees Fahrenheit).It depends if you like to sleep in a cool or warm room.
