increases
what will happen to the RELATIVE humidity?
Relative humidity will decrease.

Question 8
8.
When can dew form?
when cold air comes into contact with a warm surface
when warm air comes into contact with a cold surface
when warm air comes into contact with a warm surface
when cold air comes into contact with a cold surface
Question 9
9.
How does dew form on a surface?
Rain drops land on a surface that is colder than the air.
Water vapor condenses into water droplets on a surface that is cooler than the air.
Water vapor condenses into water droplets on a surface that is warmer than the air.
Rain drops land on a surface that is warmer than the air.
Question 10
10.
How does frost form on a surface?
The air is cold enough to snow and the snow lands on a cold surface.
Rain droplets freeze on a cold surface.
Water vapor changes into a solid ice crystal on a surface that is below freezing.
Water vapor condenses then freezes into an ice crystal on a surface that is below freezing.
