Water Molecules are polar molecules. That means that one end of the molecule has a slight positive end and one end has a slight negative end. Then just like a magnet, the positive end poles the negative end connecting the two.

Do molecules rise or sink after they are heated?
Rise
Why does the boiling point of water rise if salt is present?
The salt reduces the number of water molecules from escaping the surface into the air. Thus, the water has to be at a higher temperature to be able to push the salt molecules aside and finally reach the surface and evaporate.
Can a liquid dissolve a gas?
There are a number of ways in which a gas could dissolve in a liquid. It could bind with the liquid molecules.
Does volume of water affect temperature rise in reaction between calcium oxide and water?
If lots of water is added then the temperature will rise
Cohesion and adhesion are?
Information used from Prentice Hall Biology book from the year 2006. Cohesion is the attraction between molecules of the same substance. Due to hydrogen bonding water is very cohesive. Water's cohesion causes molecules on the surface of the water to be drawn inward causing "surface tension". This property allows insects to walk on water. Adhesion is the attraction between molecules of different substances. Adhesion causes water to rise in a narrow tube against the force of gravity for example the forces that draw water out of the roots of the plants and up into its stems and leaves, this is called capillarity.
Describe the biological significance of the cohesiveness of water?
Well, one really big and well known reason is that it allows water to be transported through plants. The sun exaporates water and cohesion allows the water to be sucked up to the leaves from the bottom even with gravity pulling down on it because of the constantly reformed hydrogen bonds.
What property of water gives rise to capillary action?
Cohesion force among the molecules of water allows for capillary action in plants.
What is the tendency of water molecules to stick to molecules of another substance?
The ability of water molecules to stick to one another is due to cohesion. Cohesion is what gives rise to properties such as surface tension.
Why level of water does not rise when sugar crystal dissolves in water?
The sugar molecules separate and disperse in the water, occupying the spaces between the water molecules. This does not change the volume of the solution, so the level of water does not rise.
How does water rise to the top of a redwood tree?
adhesion of water to the wood and cohesion of water molecules
Why is a balloon more buoyant on a hot day?
the heat gives the molecules more energy to move around and rise.
Do molecules rise or sink after they are heated?
Rise
Why does water vapor rise when liquid water is heated by the sun?
By heating the intermolecular forces are weakened and liquid molecules can escape as a gas.
What process transport the ocean to a cloud?
Evaporation. The heat of the sun causes water to turn into air molecules and rise into the sky. Once they rise and cool off, the water vapor condenses into clouds
What happens to the average kinetic energy of the water molecules in your body when you have a fever?
The average kinetic energy of water molecules goes up. Fevers cause the internal temperature to rise which increases kinetic energies.
Why does the boiling point of water rise if salt is present?
The salt reduces the number of water molecules from escaping the surface into the air. Thus, the water has to be at a higher temperature to be able to push the salt molecules aside and finally reach the surface and evaporate.
What is a scientific term for the ability of water molecules to rise up a very narrow tube?
That's called - 'capillary action'.
