Water with salt evaporates slower than water without salt science project?
Evaporation is a surface phenomenon. In case of pure water any of the molecules of water at surface have the chance of escaping into the air but when salt is added into water some of the ions of salt will come on the surface and thus block some of the surface area which was earlier available for water molecules to escape. Hence chance of water molecules escaping into air becomes less so water with salt evaporates slower than water without salt. This effect is known as elevation in boiling point.
Why the surface of water column is concave?
The shape of the surface of a column of water actually depends on what the sides of the container are made of, but for a glass tube the surface is concave. This is because water likes to wet the glass. Some materials, such as teflon, water does not like to wet. On a teflon surface, water will form little beads and does not like to stick. A water column in a teflon tube would have a convex surface.This is because the wet glass has less surface energy than the dry glass. Since the universe always likes to reduce the total energy of a system, the water rises up the sides to make more wet surface and reduce the total energy. With a teflon surface, the dry surface has less energy and so the water is "repelled" from the surface.
Which planet doesn't contain liquid water?
None of the planets in our solar system except Earth are thought to have surface liquid water in any considerable amount. Some planets are known to have water ice or atmospheric water vapor; some moons of Saturn and Jupiter (which are not planets) show evidence of having sub-surface oceans of liquid water owing to tidal heating effects; other planets including Mars and Venus (both of which were thought to have significant amounts of surface water in their history) continue to be studied for the possibility of liquid water below the surface.
Some bacteria are greenish in color and live on the surface of water These organisms are probably?
parasites
What does groundwater mean in the water cycle?
Large Underground deposits of water underneath the earth's surface.
Some insects can stand on the surface of water because water?
Some insects can stand on the surface of water because water is usually adhesive and cohesive. This is made possible by the molecules in the water.
Problems with submarines?
All submarines can sink. Some can return to the surface.
Is there water on of Mars?
not on the surface but might be some under the surface of the planet...??
Is there any liquid water in the moon?
no Not on the surface; some speculate that there may be frozen water beneath the surface.
Do some groundwater return to the surface?
Some ground water will return to the surface. This can be seen especially near large bodies of water. Areas that flood will have returning water as well.
Does some groundwater return to the surface?
Some ground water will return to the surface, especially during flooding. At times, areas near bodies of water will have returning ground water in spots.
What are some environmental problems of an octopus?
water
Is surface water Clean?
Only in some rivers.
Where can water be found on Mars?
there is frozen water on mars some where under its surface
What are some problems with water?
pollution, people in some places arent getting enough water
The ability of some organisms to be able to walk on water is due to which property of water NAME the property?
The property of water allowing some insects and other animals to walk on its surface is called "surface tension".
What is a sentence with the word surface tension?
Some insects can stand right on the surface tension of the water.
