The attraction between water molecules and another substance is called adhesion. An example of this phenomenon is the absorption of water by a towel.
Water molecules are also attracted to each other by cohesion.
Adhesion and cohesion of water are both caused by the polarity of water molecules.
Molecules are said to be polar if they have opposite electrical charges at different ends of the molecule. Nonpolar molecules have none or evenly distributed charges (oil is an example of a nonpolar substance).
Since opposite charges attract, water is attracted to other polar (or ionic) substances.
Yes, water is a good dielectric because it has a relatively high dielectric constant compared to other substances. This property allows water to effectively reduce the strength of electric fields and act as an insulator in many applications, such as in capacitors and electrical systems.
Water is not particularly heavy compared to other substances. It has a density of 1 gram per cubic centimeter, which is lower than many metals and some other liquids.
The resonance frequency of the water molecule is important because it influences its ability to absorb and release energy. This property affects how water interacts with other substances, such as forming hydrogen bonds and having a high specific heat capacity. Understanding this frequency helps explain why water has unique properties like being a universal solvent and having a high surface tension.
No, water is not completely incompressible, but it is very difficult to compress compared to other substances.
Mixing with water is a physical change because the chemical composition of the substances remains the same before and after mixing. Physical properties refer to characteristics that can be observed or measured without changing the composition of the substance.
Adhesion is when water molecules stick to other molecules
Cohesion .
Cohesion .
No, boiling point is a physical property of a substance, not a chemical property. Chemical properties describe how a substance interacts with other substances to form new substances.
No, a reaction with many substances is not a physical property of water. Physical properties of water include its boiling point, density, and color, whereas the ability to undergo reactions with different substances is a chemical property.
When water is polar, it means that it has a slight positive charge on one end and a slight negative charge on the other. This property affects its interactions with other substances because it allows water to form hydrogen bonds with other polar molecules, such as salts and sugars. This makes water a good solvent for polar substances and helps it dissolve and transport nutrients in living organisms.
it is a chemical property because it changes the chemical structure of the molecules in the base

It contracts when heated from 0 deg C to 4 deg C. Other substance expand when heated.
Solvent Property
cohesion causes water to adhere to itself. Adhesion causes water to adhere to other things. These two properties together allow for the "wick effect" a.k.a. capillary effect of water where water will actually climb tube.
