How do you prove the presence of water vapour In air?

Answer 1

take a very cold beverage out of the fridge and let it sit on the counter for a minute or two, if you are not in an air conditioned building there should be condensation on the surface of the can, proving that water vapor is in the air.

Answer 2

You can prove the presence of water vapor in air by using a hygrometer or a psychrometer to measure the humidity level. Another method is to observe condensation on a cool surface, such as a mirror or glass, which indicates the presence of water vapor in the air. You can also use a dew point hygrometer to measure the temperature at which dew forms, providing evidence of water vapor.

Answer 3

When you steal buy a cold drink, and leave it in the open, you will observe that liquid water forms on the surface of the container. That is water vapour from the air that came in contact with the surface of the container of the cold drink and was condensed due to the low temperature of the cold drink..

Answer 4

First take a glass and fill it with ice cubes. Then after sometime observe that water droplets will appear surrounding the glass. This water droplets show that water vapour is present around in the air because the water vapour in air will condense and form into water droplets.

Answer 5

the particles of water'when boling the water the particles of water changes into vapour when you boiling the water firs you cover the jug,like plate you boiling so u can see the water droplets in plate.

Answer 6

Take the air in a sealed glass container then cool the sealed container. If water vapour is in the air in the container then it will come out of solution and condense on the container inside when cooled.

Answer 7

Take a solid object and cool it in the refrigerator for a few hours. Take it out and let it sit. After a few minutes water vapor from the air will condense onto its surface.

Answer 8

i really don't know but please please tell me what it is.

Answer 9

From experience: When bicycling through a low lying mist, water vapour will condense on your person and clothes, so proving that there was water vapour in the air at the time.

Answer 10

Some evidence that there is water vapor in the air include clouds, feeling moisture on our skin on a humid day, and seeing droplets form on the outside surface of cold drinks (condensation).
