Question

Give reason : At dawn, in winter we see dewdrops on leaves of tree

Answer 1

The air contains moisture.In early morning specially in winter the temperature is less i.e. , air is cool. At this temperature air cannot hold all the moisture in it. The excess moisture condenses on cool surface like leaves, grass, car glasses, etc in the form of dewdrops. Hence we see dew drops on winter morning.

Answer 2

This is because,when the dewdrops are flow in air and due to slow winds the dewdrops are colloid and fall down in leaves of trees.
