Water is highly cohesive—it is the highest of the non-metallic liquids. More precisely, the positive and negative charges of the hydrogen and oxygen atoms that make up water molecules makes them attracted to each other.
Why does water molecules attract each other and tend to stick together?
Water molecules tend to stick together due to the structure and charge of the atoms present in the water. This means that the hydrogen atoms of one water molecule are attracted to the oxygen atom of another water molecule since opposite charges attract.
How fast do water molecules move?
approximately 590 m/s
The faster a molecule moves, the more kinetic energy it has, and the higher the measured temperature. When water is at room temperature (20 °C or 68 °F), the average speed of the water molecules in the water is approximately 590 m/s (≈1300 mph). But this is only the average (or mean) speed of the water molecules.
Why does water hold together?
This sticking together of like substances is called cohesion. Depending on how attracted molecules of the same substance are to one another, the substance will be more or less cohesive. Hydrogen bonds cause water to be exceptionally attracted to each other. Therefore, water is very cohesive.
Why are all water molecules attracted to each other?
More precisely, the positive and negative charges of the hydrogen and oxygen atoms that make up water molecules makes them attracted to each other. Opposite magnetic poles attract one another much like positively charged atoms attract negatively charged atoms in water molecules. Click to see full answer.
How are oxygen and hydrogen atoms related in a water molecule?
In a water molecule, the oxygen atom and hydrogen atoms share electrons in covalent bonds, but the sharing is not equal. In the covalent bond between oxygen and hydrogen, the oxygen atom attracts electrons a bit more strongly than the hydrogen atoms.
What do you notice when water molecules orient themselves?
The negative area near the oxygen atom is red, and the positive area near the hydrogen atoms is blue. Project the animation Polar water together. What do you notice about the way water molecules orient themselves?
Opposite magnetic poles attract one another much like positively charged atoms attract negatively charged atoms in water molecules.
