Every summer a family in Wisconsin goes on vacation to a campground near a deep lake. One year the family decided to take an RV camper to the lake for a quick trip in the winter. The family noticed that the lake was completely frozen over, but several other visitors were ice fishing and catching loads of fish. Which property of water explains why the lake did not freeze through and kill the fish?
|
|
Water’s polarity encompasses fish and allows them to break through ice.
|
|
|
Liquid water is less dense than ice, causing the ice to float to the top and support the fishermen.
|
|
|
The high specific heat of water means that the water will freeze slowly. Since water freezes so slowly, it gives the fish enough time to escape to the bottom of the lake.
|
|
|
The water molecules in ice are more spread apart and less dense than the water molecules in liquid water, causing the ice to float on the surface.
