Hot air, but it can damage your hair.
Because hot air makes heat and makes you hair darker , so cool and cold air makes your hair cooler and grow fast to get you warm for next winter
well, blow dryers are a good type of way to dry your hair and it blows HOT air but if you use cold air its still okay. but to cold would make your hair freeze so i would probably say hot air
Hot air dries clothes faster than cold air.
the cold air is making the water in your hair cold which makes your hair cold. if your hair is dry then there is no water in i for the hair to be as cold as it is when its wet.
Warm air makes fog appear faster, as the warm air can hold more moisture than cold air. When warm, moist air comes into contact with cooler air, it cools and can no longer hold all the moisture, leading to the formation of fog.
getting the engine worked on and put in a cold air intake
Generally, cold air will not do anything for any glue. Some adhesives,especially many epoxies will benefit from warm air. Some other adhesives, particularly those with 100 % silicon will harden faster under cold,running water.
Hot air diffuses faster than cold air because the molecules in hot air move more quickly, spreading out and mixing with the surrounding air at a faster rate. Cold air molecules move more slowly, resulting in slower diffusion.
it travels faster in warner air since cold particles dont move very fast because they do not have much energy. then when warm air enters the particles they start moving faster and vibrating faster which moves sound along alot faster. hope this helps :).
A hair dryer uses hot air instead of room temperature air, thus drying you hair faster.
A hair dryer blows hot air out.
In heat because the moisture in the air will make the bread mold
