Because they get used to the air around them so the water becomes that temperature.
Unchlorinated water, such as bottled distilled water is best.
You should keep the water at room temperature.
The water should be at room temperature.
Just leave the aquarium at room temperature.

Your breath should be warmer than room temperature unless you are a zombie! I am guessing you are asking why does blowing on your wet finger feel colder even though your breath is warm? Moving air allows the water on a wet finger to evaporate faster. Evaporation of a liquid to a gas requires energy and the water is taking that energy from your finger. Less energy means a lower temperature and your finger gets cold.
A Jolly Rancher will dissolve faster in hot water compared to room temperature water. The higher temperature of the hot water increases the rate of the dissolving process, allowing the candy to break down more quickly.
It depends on the fish. If its a tropical fish that is accustomed to salt water, you need salt water and you need to keep the water at a warmer than norm temperature. If its just a regular goldfish, freshwater at room temp should do just fine.
I don't know if it is normal or not, but my sister had goldfish that would jump out of their tank when she would walk into the room. She would have to scoop them up and put them back in.
Yes she does in here living room floor because she loves water.
