Water has several properties that make it unique amongst compounds and make it possible for all forms of known life to function. The graph provided depicts what happens to the density of water as the temperature gets colder. According to the graph, what happens to the water’s density as it freezes and why? (SC.912. L.18.12)

When the temperature of the water finally goes below 4°C, the density of water decreases and as a result ice does not sink. The surface water freezes at 0°C while the lower part remains at 4°C

When the temperature of the water finally goes below 4°C, the density of water increases and as a result, ice doesn’t sink. The surface water freezes at 0°C and the water below freezes as well, allowing life to exist below frozen lakes

Water continues to get denser as the temperature get colder

The properties of cohesion and adhesion are directly responsible for water expansion at 4°C allowing aquatic life to survive under frozen lakes

Respuesta :

Water’s density increases as it freezes or at lower temperature which is a unique property of water that enables aquatic animals to survive.

How cold water has more density?

Cool water has more density because cooling a substance leads to molecules to slow down and get closer to one another, occupying a smaller volume that results in an increase in density while on the other hand, the warm water is less denser and will float on room-temperature water.

So we can conclude that cold water is more dense and will sink in room-temperature water.
