Question

Why doesn't sweat evaporate on a humid day?

Answer 1

maybe the sweat contains too much salt and oil to evaporte.  Fresh was evaporates faster.  Right?

Answer 2

it has too much oil in the sweat.

Answer 3

Humid days are ones in which the amount of moisture in the air is already high. Sweat evaporates by becoming moisture in the air. So, if the air is already pretty well saturated with moisture, there's no where for the sweat to go.

Answer 4

When the humidity is high, sweat cannot evaporate as easily due to the air being heavy already with to much moisture.

Answer 5

heat!

Answer 6

The air is holding all the moisture that it can. When you hear on the news what the relative humidity is, that is a measure of the amount of moisture in the air, relative to what it can hold. The lower that is, the faster moisture can be absorbed (like into a dry cloth). the higher it is, the harder that it is for more moisture to evaporate into the air (just like a damp cloth)

Answer 7

Because there is too much moisture in the air to allow any more to evaporate into it.
