Which substance has a stronger inter molecular force stearic acid or melting temp of water?
Stearic acid since it is nonpolar and H2O is polar.
How the melting point of alkenes can be increase by increasing molecular mass?
Melting points are determined by the strength of interaction between molecules in a solid. The greater the force of interaction, the higher the melting point. Molecular interactions are the result of the attraction between partially charged molecules or ions in a solid. Alkenes have little or no charge; they are nonpolar. In order for alkenes to stick to each other in a solid, they need to have partial charge induced randomly. This is known as London Dispersion Force. The probability of a partial charge occurring is increased when the size of a molecule's electron cloud increases. Bigger alkenes have bigger electron clouds, and thus have more powerful London dispersion force. More intermolecular force means higher melting points.
Which matter has the minimum inter molecular force?
Intermolecular forces are weak in gases.
Is cohesion and adhesion the same?
No, Cohesion is when like particles are forced together by the molecular forces. Adhesion is when unlike particles are forced together by molecular force
Which force must be overcome to melt Krypton?
Krypton is gas and does not need melting.
Why do molecular substances with weak inter-molecular forces have low melting points?
The cause is just this weak intermolecular force, ease to be broken.
What force cause runoff?
melting snow
Which substance has a stronger inter molecular force stearic acid or melting temp of water?
Stearic acid since it is nonpolar and H2O is polar.
Which has a higher boiling point CO2 or SiO2?
intermolecular force between the sio2 molecule is greater than that of the co2 molecule....the co2 molecule is in it gaseous state while that of the sio2 is crystalline making the intermolecular force stronger than that of the co2 molecule.
What attractive force would cause the highest boiling point?
These are ionic bonds.
Why iodine molecule has low melting point?
Iodine molecule , I2 has a low melting point because it has simple molecular structure which is held by weak Van der Waals force. Hence small amount of heat required to break the bond.
Why do molecular solids usually have lower melting points than ionic solids?
The electrostatic force between the positive ions and the negative ions are very strong, so it requires a large amount if energy to break them. The attractive force between covalent molecular is weak, so less heat energy is required to break it.
What is molecular force?
The force between two molecules.

What is an example of autogenous welding?
An autogenous weld is one where filler metal is not used for joining. the weld is produced by fusion of the parts by melting. It does not use force to bond the parts, only the heat produced which cause melting of the base materials.
What does the gravitational force in a molecular cloud depends on?
Density
