Adhesion: attractive force between 2 particles in different substances, like water and glass molecules
Cohesion: attractive force that holds molecules of a single substance together, like the surface tension on water
It is the force exerted on a liquid molecule by neighbouring molecules
or
it is the force of attraction betweenthe particles of of same substance
The amount of energy required to bring atoms from infinite distance to finite distance (or)
The amount of energy released to bring atoms from infinite distance to finite distance
Force between inter molecules of water is termed as Cohesive Force
Lattice energy is energy required to separate ions to infinite distance with no more interaction. Cohesive energy is energy required to separate atoms to infinite distance with no more interaction.
The purpose of a cohesive device is to link words or sentences together.
To calculate the cohesive energy, let us consider the general situation of two identical atoms. As the atoms approach, the attractive forces increases and potential energy decreases. At the equilibrium position the potential energy of either two atom is given by U= decrease in potential energy due to attraction + increase in potential energy due to repulsion. work done in moving through a small distance dr is given by du(r) + F(r)dr Hence the potential energy if the atom U(r)=int du(r) = int F(r)dr = int(A/rM - B/rN)dr
The arrow has combustible material coated on certainrestrictedarea of the arrow. This materials in coated form has highest potentialenergydue to stronger cohesive forces. when thismaterialswith stronger cohesive forces catch fire the molecules or the particles of the coatedmaterialgain higherkineticenergyby weakening cohesive forces. thekineticenergyof the particles faces resistanceand thus the kineticenergyis noted as frictional forcesbecausethe flame which withhigherkineticenergymoves forward faces resistance and flame may not go to more and more distance from the arrow area. Thus the cohesive and frictional forces do operate in flame movement or it could be termed as Friccohesity is highly operative factor for converting potentialenergyinto the kineticenergyof thematerialsin flame phenomenon.
Intermolecular forces are stronger in liquids than in gases. A gas is the physical state characterized by the complete dominance of kinetic energy (disruptive forces) over potential energy (cohesive forces). Thus, gas particles move independently of one another. On the other hand, a liquid is the physical state characterized by potential energy (cohesive forces) and kinetic energy (disruptive forces) of about the same magnitude. So, the particles in the liquid have enough kinetic energy to move and slide past one another, but are still held together by any intermolecular forces. The particles in the liquid will break free of any intermolecular bonds once they obtain enough kinetic energy.
Lattice energy is energy required to separate ions to infinite distance with no more interaction. Cohesive energy is energy required to separate atoms to infinite distance with no more interaction.
If you think to lattice energy the value is 789 kJ/mol.
Yes the particles of clay stick together when not suspended in water- this is what makes it cohesive, however when in water the clay particles separate and so can be held in suspension with almost nul energy!
Cohesive
The team presented a cohesive plan for the project, demonstrating their strong unity and organization.
Cohesive soil: A sticky soil, such as clay or silt; its shear strength equals about half its unconfined compressive strength. Non-cohesive soil: loose, sandy material which does not bond together very well. Therefore, cohesive soil is a better foundation than that of non-cohesive.
Friction and cohesiveness are the only differences. The matter has stronger potential energy with stronger cohesive forces and the energy has stronger kinetic energy with demonstration as frictional force.
The One...Cohesive was created on 2011-01-01.
A quite simple sentence is: "I do not know what cohesive means."
This is a cohesive interaction.
cohesive soils are those soils where the attraction between the soil particles is very high such as in clay. non-cohesive soils are those soils where there is no firm attraction between the soil particles.
The purpose of a cohesive device is to link words or sentences together.
