Water molecules stick to each other to form a sphere. This is the result of cohesive forces. When contained in a tube, the water molecules touching the surface of the container are at a higher level (see Meniscus). This is due to the adhesive force between the water molecules and the molecules of the container.
Intermolecular forces are the forces that are between molecules. And so that's different from an intramolecular force, which is the force within a molecule. So a force within a molecule would be something like the covalent bond. And an intermolecular force would be the force that are between molecules.
Magnetic Force You probably have played with magnets and might have noticed that two magnets exert a force on each other. Depending on which ends of the magnets are close together, the magnets either repel or attract each other. You might have noticed that the interaction between two magnets can be felt even before the magnets touch.
Oct 25, 2018 · Intermolecular forces is a general term describing the fact that all atoms, and molecules share a certain inherent attraction for each other. These attractive forces are much weaker than the bonds that hold molecules together, but in a large cluster of atoms or molecules the sum of all of these attractive forces can be quite significant.

In the following reactions, identify the substance that is oxidized and the substance that is reduced: 2Li(s) + F2(g) → 2LiF(s) ...The state of a substance depends on the balance between the kinetic energy of the individual particles (molecules or atoms) and the intermolecular forces. The kinetic energy keeps the molecules apart and moving around, and is a function of the temperature of the substance and the intermolecular forces try to draw the particles together.
The strongest attraction is between ions. For example, the interaction between Na + and Cl − is 787 kJ/mol. The attraction between permanent dipoles is next strongest at 8–42 kJ/mol. Finally, the weakest interaction of 0.1–8 kJ/mol is between induced dipoles. The forces between the molecules of organic compounds are mostly of the last two types.

Most candidates could write with confidence about the repulsive nature of the proton-proton interaction and the attractive nature of the strong nuclear force. Few gave good accounts of the balance between these two forces or described the energy situation (a better way to answer). Weak candidates could not name the strong nuclear force adequately.

Colloids are particles in-between 10 and 1000 nm in size, which is about one hundred times smaller than the thickness of a human hair. Colloids can be suspended in a liquid or in a gas, and some examples of colloidal systems are milk and smoke that contain fat droplets in water and sot particles in air.
Identify types of intermolecular forces Identify the relationship between the state of substances and the intermolecular forces present X-planation What forces exist inside matter? The forces inside matter are electrostatic in nature. Oppositely charged particles attract each other and like charges repel each other.

The state of a substance depends on the balance between the kinetic energy of the individual particles (molecules or atoms) and the intermolecular forces. The kinetic energy keeps the molecules apart and moving around, and is a function of the temperature of the substance and the intermolecular forces try to draw the particles together.
London Forces. Attractive forces between atoms in a substance affect its boiling point. The stronger the force, the harder it is to “pry” atoms apart from each other and turn them into a gas; elements with high boiling points require more heat energy to separate the atoms.

Ionic bond: bond in which one or more electrons from one atom are removed and attached to another atom, resulting in positive and negative ions which attract each other. Other types of bonds include metallic bonds and hydrogen bonding. The attractive forces between molecules in a liquid can be characterized as van der Waals bonds.
-particles which make up a liquid are in constant motion like those of a gas-liquid particles are free to slide (pass) over each other-both gases and liquids are said to have the ability to flow-particles of a liquid have high attraction forces between molecules, called intermolecular forces
The size of the force varies inversely as the square of the distance between the two charges. Therefore, if the distance between the two charges is doubled, the attraction or repulsion becomes weaker, decreasing to one-fourth of the original value. If the charges come 10 times closer, the size of the force increases by a factor of 100.

London Dispersion forces are due to temporary and induced dipoles from the natural repulsion between electrons and attraction of electrons to protons. L-D forces are the weakest IMF, but are the strongest in nonpolar molecules. L-D force increases as the size of the nonpolar molecule surface increases, due to a larger number of mobile electrons.

The greatest forces of attraction are between the particles in a solid and they pack together as tightly as possible in a neat and ordered arrangement called a lattice. The particles are too strongly held together to allow movement from place to place but the particles vibrate about their position in the structure.
Most candidates could write with confidence about the repulsive nature of the proton-proton interaction and the attractive nature of the strong nuclear force. Few gave good accounts of the balance between these two forces or described the energy situation (a better way to answer). Weak candidates could not name the strong nuclear force adequately.
