Are lattice and cohesive energies same?
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.
Show that cohesive energy is minimum at equilibrium separation?
We have Lennard-Jones Potential given by, U=4epsilon[{(sigma/R)^12}- {(sigma/R)^6}] At equilibrium, dU/dR=0 if U is minimum. Solving, we get U=-epsilon which is indeed the bottom of the potential well.
What is cohesive energy of a molecule?
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
Do all liquids have a cohesive force?
Yes, all liquids have a cohesive force, which is the force that holds the molecules of the liquid together. This force is responsible for the surface tension and other cohesive properties of liquids.
What kind of energy will be stored in the arrow when it is fired?
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.
What is cohesive energy in case of NaCl?
If you think to lattice energy the value is 789 kJ/mol.

Cohensive energy derivation?
Cohesive energy is the energy required to completely separate a solid into its individual atoms or molecules. It is a measure of the strength of the intermolecular forces holding the solid together and is related to the bond strength between the atoms or molecules in the solid. Cohesive energy is typically expressed in units of energy per mole or energy per unit volume.
Is clay cohesive?
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!

What are the differences and similarities between matter and energy?
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.
Use the word cohesive in a sentence?
I'm having a little trouble coming with a cohesive answer to your question. Was the glue adhesive or cohesive?
How do you write a sentence with cohesive?
A quite simple sentence is: "I do not know what cohesive means."
When was The One...Cohesive created?
The One...Cohesive was created on 2011-01-01.
Is oil cohesive?
no
What force enables the stem to absorb water?
Adhesion and Cohesion or cohesive attraction or cohesive force
