Why earth is called the blue planet?
Earth is called the blue planet because when viewed from space, it appears predominantly blue due to its oceans that cover over 70% of its surface. The reflection of sunlight off the water gives Earth its distinct blue appearance.
Why does pool water look blue?
Pool water looks blue because of the way water absorbs and scatters light. When sunlight enters the water, it is absorbed by the molecules and particles in the water, especially in the blue wavelength. This causes the blue light to be the dominant color reflected back to our eyes, making the water appear blue.
On a map what color is for water?
When you look into an ocean or a lake, the water looks like it's blue. But, up close, water isn't really blue. It's only blue when you look at it in big groups, (like an ocean or a lake, a pond etc.), because the sky is blue, so the color of the sky makes a blue reflection on the water, making it look blue. So, on a map, if you drew water as clear, nobody would be able to tell there was anything there at all! So, water on a map is drawn blue instead.
Why does the sea appear blue even though water is colorless?
The ocean appears blue because water molecules absorb light from the red part of the spectrum and scatter light in the blue part of the spectrum more efficiently. This scattering causes more blue light to reach our eyes, making the ocean appear blue.
Why does soap turn water blue?
Soap does not turn water blue. It is likely that a blue-tinted soap was used, or that the soap contained a dye or pigment that resulted in the blue color when dissolved in the water.
What happens when water is added to the blue solid?
It entirely depends on what the blue solid is! If it's copper sulfate, the solid dissolves. If it's lapis lazuli, the solid sinks to the bottom. If it's small pieces of blue fibreglass, it will probably float.
How can I keep a blue spruce small in size?
To keep a blue spruce small in size, you can prune it regularly, limit its water and fertilizer intake, and plant it in a container to restrict its growth.
Why does water appear blue in paintings and drawings but its not blue in clear drinking water?
Its hard to paint water. Simpily because in small concentrations water is fairly transparent, the blue color may be inspired from the color of the sky reflecting on the waters surface. HOWEVER water truley is a blue substance, as the depth of water increases the blue-er the water becomes. This is because of the water molecules abality to absord red light and in turn reflecting blue light.
What happens if hydrogen is reacted with oxygen?
The Hydrogen will burn fiercely with a lambent blue flame and water will be produced.
What is color of the water?
The water looks colorless when in small quantities but it has actually a very slight blue hue to it. This can be tested with a glass of water and a filled bathtub: the former will appear colorless while the latter will be faint blue.
What is the prey for a blue whale?
Blue whales are filter feeders; they filter small organisms such as krill, sardines, etc, out of the water, by use of their baleens.
Does water have a color?
Yes, it his slightly blue but it appears colorless to the human eye when in small quantities.
Where does the blue whale belong in the food chain?
They eat water, squids, mostly creatures that are small.
Test for presence of water in anhydrous copper sulphate?
To test for the presence of water in anhydrous copper sulfate, heat a small sample of the compound in a test tube. If the compound changes color from white to blue, it indicates that water is present in the compound. This color change happens as the anhydrous copper sulfate absorbs water vapor from the air, converting back into hydrated copper sulfate.
Why is ocean water blue?
Ocean water appears blue because it absorbs colors in the red part of the light spectrum and reflects blue light. This happens because water molecules absorb longer wavelengths of light, like red and orange, while shorter wavelengths, like blue, are scattered and reflected back to our eyes.
What happens if red litmus and blue litmus is dipped in sodium chloride?
Sodium chloride water solution is neutral.
What happens when you mix TAP WATERand Bromothymol blue?
When mixed with tap water, bromothymol blue will change color depending on the acidity of the water. In acidic conditions, it will turn yellow; in neutral conditions, it will be green; and in basic conditions, it will be blue. This color change is due to bromothymol blue's pH-sensitive properties.
