Is the attraction between two like substances?

Cohesion is an attraction between substances of the same kind. … Adhesion is an attraction between different substances.

Is the attraction between two like molecules?

Dipole-Dipole Attractions

Dipole–dipole interactions are a type of intermolecular attraction—attractions between two molecules. Dipole-dipole interactions are electrostatic interactions between the permanent dipoles of different molecules. These interactions align the molecules to increase the attraction.

What is the attraction between like molecules called?

Attractive forces between molecules of the same type are called cohesive forces. Attractive forces between molecules of different types are called adhesive forces.

When two like substances are attracted by hydrogen bonding it is called?

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.

Is the attraction between particles of the same substance which results in surface tension?

Cohesion is the attraction between particles of the same substance (why water is attracted to itself). This results in a high Surface tension (a measure of the strength of water’s surface).

Do particles in a substance attract each other?

Solids, liquids, and gases are made of tiny particles called atoms and molecules. In a solid, the particles are very attracted to each other. They are close together and vibrate in position but don’t move past one another. In a liquid, the particles are attracted to each other but not as much as they are in a solid.

What is the difference between a hydrogen bond and a covalent bond?

Covalent bonds are intramolecular bonds whereas hydrogen bonds are intermolecular bonds. Water is held together with covalent bonds. In covalent bonds, electrons are shared between the atoms. In water, oxygen is bonded to two hydrogen atoms.

What is the attraction between water molecules called?

In the case of water, hydrogen bonds form between neighboring hydrogen and oxygen atoms of adjacent water molecules. The attraction between individual water molecules creates a bond known as a hydrogen bond.

What is hydrogen bonding explain with example?

What is Hydrogen Bonding? … For example, in water molecules (H2O), hydrogen is covalently bonded to the more electronegative oxygen atom. Therefore, hydrogen bonding arises in water molecules due to the dipole-dipole interactions between the hydrogen atom of one water molecule and the oxygen atom of another H2O molecule.

How intermolecular forces of attraction affect surface tension?

The stronger the intermolecular interactions, the greater the surface tension. … It results when cohesive forces, the intermolecular forces in the liquid, are weaker than adhesive forces, the attraction between a liquid and the surface of the capillary.

What is the relationship between surface tension and cohesion?

Cohesion is molecular attraction between like molecules and adhesion is molecular attraction between unlike molecules. Surface tension is most directly related to cohesion. For example, the surface tension of a pool of water is due to the attraction of water molecules to other water molecules.

How intermolecular forces of attraction affect vaporization?

Strong intermolecular forces produce a lower rate of evaporation and a lower vapor pressure. Weak intermolecular forces produce a higher rate of evaporation and a higher vapor pressure. As the temperature increases, the vapor pressure increases.
