Question

How can you show that air contains water vapors? Is the water vapor constant in the air?

Answer 1

Air contains water vapors which can be proven by a simple test that is as follows:

• Take icy cool water in a container and let it be undisturbed for some 1-2 minutes.
• After 1-2 minutes we can clearly observe the drops of water on the outer side of the container.
• These water droplets are nothing but water vapors that are present in the environment and after getting lower temperatures they cooled down(condensation) and become water droplets.
• So, that is how we can prove the presence of water vapors in the environment.

Water vapor is not constant in the environment, it totally depends on the temperature of the place and the wind speed of the place.

The higher the wind speed the higher the rate of vaporization and thus high the vapors will be.The higher the temperature the higher the vaporization will be and thus higher the vapors in the environment will be.
