Air always contains some amount of water vapour at a given temperature. When the temperature of air decreases, the capacity of air to hold water vapour also decreases, and vice versa. When the temperature of air falls below a certain temperature, the excess water vapour present in the air gets transformed into very small droplets of water. This process is called condensation and the temperature at which condensation takes place is called the dew point. For condensation to take place a surface is required. Such a surface is called the nucleus. Tree leaves, grass and dust particles in air are examples of nucleii around which condensation occurs. Condensation of water vapour leads to the formation of clouds, rain, snow, sleet and hailstone.
During the day, when water bodies (oceans, lakes, ponds, etc.) are heated up by the sun, a large amount of water goes into air as water vapour.

It was a good experience with Abhyas Academy. I even faced problems in starting but slowly and steadily overcomed. Especially reasoning classes helped me a lot.
One of the best institutes to develope a child interest in studies.Provides SST and English knowledge also unlike other institutes. Teachers are co operative and friendly online tests andPPT develope practical knowledge also.
