Take a few ice cubes in a glass. Keep it on the table for a few minutes. You could see tiny droplets of water all over the outer surface of the glass. From where do these droplets come?

Why do we see water droplets on outer surface of a glass containing ice - cold water?

Arrange the following statements in correct sequence: 1. These vapours condense to form tiny droplets of water. 2. The water droplets come together to form large water droplets. 3. The heat of the sun causes evaporation of water from the surface of the earth, oceans, lakes, rivers and other water bodies. 4. The large water droplets become heavy and the air cannot hold them, therefore, they fall as rains. 5. Water vapour is also continuously added to the atmosphere through transpiration from the surface of the leaves of trees. 6. Warm air carrying clouds rises up. 7. Higher up in the atmosphere, the air is cool. 8. These droplets floating in the air along with the dust particles form clouds.

A glass contains some water at room temperature 20^(@)C .Refrigerated water is added to it slowly. When the temperature of the glass reaches 10^(@)C, small droplets condense on the outer surface. Calculate the relative humidity in the room. The boiling point of water at a pressure of 17.5mm of mercury is 20^(@)C and at 8.9mm of mercury is 10^(@)C .

Ramu and Raju are dragging water in a bucket from the wells A and B respectively. Ramu dragged three buckets of water within 5 minutes but Raju could not do for the short interval of time. He could take only two buckets of water in 7 minutes. What do you inter from this Incidence. What is the expression and unit for power ?
