Question
[CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
|
|
|
The hydrogen bonds of water expand during the freezing process, creating more volume and decreasing density of the ice.
|
|
|
The bonds, between the water atoms, break expanding the ice molecules so that liquid water can fill the spaces in between the frozen water molecules.
|
|
|
The water’s cohesive properties keeps the molecules close together, therefore, increasing the density ice.
|
|
|
A lower pH makes the water more acidic, resulting in the neutral ice floating.

Detailed explanation-1: -Answer. Answer:The hydrogen bonds of water expand during the freezing process, creating more volume and decreasing density of the ice.
Detailed explanation-2: -Right when the water freezes to ice, the ice becomes significantly less dense than the water and continues to float on the lake’s surface. Below 4° Celsius, water becomes less dense as it gets colder, causing water about to freeze to float to the top.
Detailed explanation-3: -Like many people, fish tend to be less active in the cold. As cold-blooded creatures, their metabolism dips when temperatures take a dive. The layer of ice that forms on top of a lake, pond, river, or stream provides some insulation that helps the waterbody retain its heat.
Detailed explanation-4: -The reason is that ice is a poor conductor of heat hence once the surface is frozen no further heat is liberated or absorbed by water beneath ice. Therefore water below ice never freezes.
Detailed explanation-5: -Most of the water under the ice is 39 Fahrenheit; however, there is a thin layer of water under the ice that is colder than 39 and therefore less dense.
