When 8 droplets of water of radius 0.5 mm combine to form a single droplet. The radius of it is ..........

A

4 mm

B

2 mm

C

1 mm

D

8 mm

Text Solution

Verified by Experts

Volume of 8 droplets of water = `8xx 4/3 pi (0.5)^(3)`
When each droplet combine to form one volume remains conserved
`R^(3) = 8 xx (0.5)^(3)`
`R^(3) = (8 xx (0.5)^(3))`
`R = 2 xx 0.5` = 1 mm

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.
