____ [38]

Frozen water is less denser than liquid water so that's why ice floats on the water in cold areas.

<h3>Is frozen water more or less dense than liquid water?</h3>

Ice is less dense than liquid water because when the water becomes solid due to low temperature, the density of ice become decreases. Due to less density, the ice floats on the water surface.

Water is attracted due to its polar nature so adhesive forces pull the water toward other molecules. Water is transported in plants through both cohesive and adhesive forces. These forces pull water and the dissolved minerals from the roots to the upper parts of the plant.

So we can conclude that frozen water is less denser than liquid water so that's why ice floats on the water in cold areas.

Answer:

B. The rating number means it will  protect you that many times  longer than without sunscreen

Explanation:

The sun protection factor is a comparison between the length of time it will take for a skin that has no sunscreen to begin reddening compared to a skin with sunscreen applied. Therefore, the ratings is an indication of the length of time a person will be protected from ultraviolet rays than when the individual has no sunscreen applied.

While higher SPF's are believed to offer more protection against UV rays, the added protection is usually just a negligible amount. They are very important for the skin and protect the body against diseases like cancer.
