The forces between hydrophilic and hydrophobic silica particles and an air bubble were measured in pure water and in NaCl solns. using an at. force microscope. In addn. to the expected double-layer and van der Waals forces, strong long-range attractive forces were also obsd.
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.
Q1 and Q2 : Charges on the particles d: distance between their centers. 5. Arrange the following in increasing Lattice Energy. KBr, MgO, KF, AlN, MgS. Justify your answers. Importance of Size of Ions. O2-, F-, Na+, Mg2+, and Al3+ comprise an isoelectronic series since each has the same total number of electrons, 10. Yet the sizes of the ions ...
Aug 22, 2019 · Dispersion forces that develop between atoms in different molecules can attract the two molecules to each other. The forces are relatively weak, however, and become significant only when the molecules are very close. Larger and heavier atoms and molecules exhibit stronger dispersion forces than do smaller and lighter atoms and molecules. F 2 ...
