How will you show the presence of water vapous in air ...?
Answers
HEY MATE,
TO TEST THE PRESENCE WE WILL CONDUCT A SMALL EXPERIMENT...
Components of Experiment - A Glass filled with Ice cubes
EXPERINMENT -
Keep the Glass at room temperature for a while. Within a few minutes, you will see water droplets condensing on the cold surface of the glass or steel container. You can check that the drops are made of water by collecting them and tasting the liquid.

You can check that the drops are made of water by collecting them and tasting the liquid.From where did the drops come? From the water vapour present in the air. As the temperature of the air in immediate contact with the cold surface of the glass or steel container goes down, the capacity of the air to hold water vapour (called the Saturated Vapour Pressure) decreases and the excess water vapour condenses on the cold surface.
