What causes the forces of attraction?
The attraction occurs when two objects of opposite charge are in close proximity, and the electrical force causes these objects to attract. Therefore, positive and negative charges will attract each other.
What are the factors affecting the intermolecular force of attraction?
– temperature – pressure – The kinetic energy of the particles. – The strength of the attractions between the particles. Molecules/atoms can stick to each other. But much more weakly than a bond.
What are intermolecular forces due to?
Intermolecular forces are electrostatic in nature; that is, they arise from the interaction between positively and negatively charged species. Like covalent and ionic bonds, intermolecular interactions are the sum of both attractive and repulsive components.
What causes the attractive forces between particles in matter?
The particles that make up some matter are close together and vibrate back and forth. … If the motion of particles slows the particles move closer together. This is because the attraction between them pulls them toward each other. Strong attractive forces hold particles close together.
What are attractive forces in physics?
Definitions of attractive force. the force by which one object attracts another. synonyms: attraction. Antonyms: repulsion, repulsive force. the force by which bodies repel one another.
What causes weak intermolecular forces?
Dispersion forces are weak intermolecular forces caused by temporary dipoles.
Which intermolecular forces depend on the polarizability of molecules *?
As polarizability increases, the dispersion forces also become stronger. Thus, molecules attract one another more strongly and melting and boiling points of covalent substances increase with larger molecular mass. Polarazibility also affects dispersion forces through the molecular shape of the affected molecules.
When molecules have weak intermolecular forces of attraction?
All atoms and molecules have a weak attraction for one another, known as van der Waals attraction. This attractive force has its origin in the electrostatic attraction of the electrons of one molecule or atom for the nuclei of another, and has been called London dispersion force.
What are the types of intermolecular forces of attraction?
There are three types of intermolecular forces: London dispersion forces (LDF), dipole- dipole interactions, and hydrogen bonding.
What causes a dipole-dipole force?
Dipole-dipole interactions occur when partial charge form within a molecule because of the uneven distribution of electrons. Polar molecules align so that the positive end of one molecule interacts with the negative end of another molecule.
How is the intermolecular force of attraction dependent upon the intermolecular space?
Answer: More the intermolecular space, lesser is the force of attraction. … The intermolecular space is the highest in gases and so the force of attraction is almost negligible.
