because you are allowing more of it to be exposed to water. it is called heat transfer. while the oxygen is much cooler than the cup itself, it will cool the cup. this happens without stirring, but with stirring, you are increasing the "surface area" (the parts that are at the bottom are being exposed) which speeds up the process.
give me trust point? (:

When we blow over the drink, we give the particles more energy. Some of the particles with more energy escape into the air. As the particles with the most energy have escaped, it leaves the average particles in the liquid. The temperature of the average particles decrease, which result into the drink cooling down.

Marty poured hot water into his cup and then let it cool off. what was happening to the paticiles of matter in the cup as the water cooled off?
the water molecules are getting cold
Can you be at risk if you put hot water in a plastic cup and then freeze it?
The cup may be damaged.
How fast does hot water cool?
Basically, the rate at which the water will cool depends on the difference between the water's temperature, and the temperature of its surroundings. The higher the temperature difference, the faster it cools. There are some other factors, but that's the gist of it...
Would a sugar cube melt fast in a cold cup of water?
No, it wouldn't. a sugar cube would melt a lot faster in a cup of Hot water. the hot water helps it desolve more evenly than cold water.
What cup is easier to hold with hot water a plastic one or metal?
a styrofoam cup. i tried it on my science project
What is the fastest way to cool a cup of hot water?
with a cup with ice and coolwater
What happens when you put a cup of boiling water next to a cup of ice water?
the warmth from the hot water will go to the cool water and it will make both waters cool
Marty poured hot water into his cup and let it cool off what were the particles of matter doing as the water cooled?
hot bioilling water
How can you take heat away from water?
Hot water will cool if placed in a cool area. Or pouring hot water back and forth between two vessels (pans, jugs, etc). Blowing on a hot cup of tea is a common method.

What will happen energetically to a cup of boiling hot water that is added to a cup containing a cold piece of metal?
choices are: The cold will flow from the metal into the hot water, causing the hot water to warm up and the metal to cool down. b. The energy from the hot water will flow into the cold metal, cooling the water down and heating up the metal. c. The cold will flow from the metal into the hot water, causing the hot water to cool down and the metal to warm up. d. The metal will cool down because the specific heat of water is high.
How do you make a hot curry cool?
Warm it and add yogurt or some cream about half a cup with some water.
Can hot ice cool water?
I don't think that is possible. How can "hot" make "cool" water "cold"? (also, 'hot ice' is boiling water)
Why does water not form on the outside of a cup when you have a hot drink?
Hot cup evaporates water while cold water condenses water .
How are the water molecules positioned in the hot cup?
The molecules in a cup of hot water are spaced farther away from eachother than the molecules in a cold cup of water.
What type of cup keeps hot water hot the longest?
A metal cup
Why does water without ice stay the same in a plastic cup?
The plastic cups I can get have thin walls. This means the water without ice stays as water because any temperature changes to the water will not last very long. Insulated cups have thick walls so they will cool liquids cool and hot liquids hot
