Hot air, but it can damage your hair.
In heat because the moisture in the air will make the bread mold
Hot air dries clothes faster than cold air.
Because the cold air makes them grow faster
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.
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.
When the air is humid and the glass is cold.
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
A balloon expands when exposed to heat as the air particles inside it move faster, causing the balloon to inflate. Conversely, a balloon shrinks in cold temperatures as the air particles slow down, reducing the size of the balloon.
