Growth of Ice on Lake

Lakes

A: The rate of growth of ice on the surface of a lake decreases with increase in thickness of Ice layer. R: Ice is poor conductor of heat energy.

What do we call the extensive growth of algae in a lake?

Thickness of ice on a lake is 5 cm and the temperature of air is -20^(@)C . If the rate of cooling of water inside the lake be 20000 cal min^(-1) through each square metre surface , find K for ice .

Thick ness of ice on a lake is 5 cm. and the temperature of air is -20^(@)C. If the rate of cooling of water inside the lake be 20000 cal mi n^(-1) through each square metre surface, find K for ice.

Assertion Phosphours and nitrogen compounds in a lake, favour the luxuriant growth of algae. Reason Water bloom condition occurs in eutrophic ponds.
