If it takes 2 hours to form a layer of ice 2 cm thick on the surface of a lake, after how many hours would the thickness of the ice get doubled?
Interesting. Do you know what temperature is required for ice to form on a lake's surface?
Yes, typically water needs to be at or below 0 degrees Celsius for it to freeze and start forming ice on the surface of a lake.
