What is an intermolecular force?
Intermolecular forces are any forces exerted on neighboring molecules of a given compound. The forces are not the actual chemical bonds present in the substance, but rather the substances own attractiveness to its own molecules. These intermolecular forces play a crucial role in determining a compounds various physical properties such as but not limited to :solubility, melting point, boiling point, density.
Is methane a compound consisting of molecules held together by weak intermolecular forces?
Given that methane is a gas at room temperature, we can see that its molecules are attracted to each other only by weak intermolecular forces. But normally, if I say "methane is a compound consisting of..." the statement concludes, one carbon atom and four hydrogen atoms. That's what the methane molecule consists of.
Name three factors that influence the rate at which a solute dissolves in a solvent?
Bonding, polarity of the particles, and intermolecular forces between particles determine if a solute will be soluble in a given solvent.
What occurs when a objects reaches boiling point?
The substance goes from being a liquid to being a gas.The difference in terms of the molecules is that in a gas, the intermolecular forces are all broken and each molecule is not attracted to the other neighboring molecules. The molecules in the gas phase are free to move about in air.A common example of this is water turning to steam when it boils. Steam is just water in the gas phase.In a liquid, there are still attractive forces between molecules, but not as much as in a solid, where the stronger intermolecular forces keeps the substance hard and rigid.
How do van der Wals forces hold molecules together?
When molecules are close together, a slight attraction can develop between the oppositely charged regions of nearby molecules. Apex------They form temporary, weak dipole attractions between molecules.

How does intermolecular forces of a substance determine the phase the substance is in?
The strength of the intermolecular forces will determine what phase the substance is in at any given temperature and pressure. Consider the halogens for example, fluorine and chlorine are gases, while bromine is a liquid and iodine is a solid at room temperature. When considering the intermolecular forces present, each of these substances only has London forces, which increase in magnitude with increasing size of the molecules, and size increases as you go down a group in the periodic table. So, fluorine has the smallest intermolecular forces, and iodine has the largest. This explains why these different substances exist in different phases when at room temperature and pressure. The molecules in fluorine, for example, are only slightly attracted to each other, and therefore the substance exists as a gas. The stronger intermolecular forces in bromine, however, hold the molecules close to each other, but not quite strongly enough to prevent the molecules from sliding past each other; this makes bromine a liquid. Finally, in iodine, the intermolecular forces are actually strong enough that the molecules are held in fixed positions relative to each other, thus making iodine a solid.
Why cl2 is gass and br2 liquid and I2 solid?
NaCl is ionically bonded with stong electrostatic attractions whereas Cl2 only has weak Van Der Waals' forces acting between the molecules More strength is needed to break NaCl's bonds than CL2's bonds. Therefore, NaCl is solid and Cl2 is a gas Hope this helps :)
How do intermolecular force affects whether a substance is a solid at room temperature?
The stronger the intermolecular attractions are between two molecules, the more likely they are to stay together at a any given temperature.

When heated how does liquid change?
when the liquid is heated the molecules are given kinetic energy, this causes them to move faster. As the molecules move faster they collide and the cohesive (intermolecular forces/hydrogen bonds) forces break down. this means they are free to move more and their density decreases until they change state and become a gas.
Process of vaporization require an input of energy?
Yes, the process of vaporization does require an input of energy. The energy is required to break the intermolecular forces of a given substance. The intermolecular forces is usually very strong.
Does a gas have more moleules than a liquid?
No. The state of a substance does not tell the number of molecules present. In a gas, the molecules move more freely than in a liquid as they are not bound to each other by intermolecular forces. If you're going by volume, a given volume of a gas will generally contain fewer molecules except at very high pressures.
Why is E-stilbene solid and Z-stilbene liquid?
The attractive forces between the molecules in E-stilbene must be stronger than the attractive forces holding Z-stilbene together. The degree of attraction between molecules in a substance always accounts for its state of matter at a given temperature.
Does a large covalent molecule generally have a low boiling point?
Boiling point of a molecular substance depends on the intermolecular forces - forces that attracts a molecule to its neighbours of the same kind.For a covalent molecule, the possible intermolecular forces aredispersion forcesdipole-dipole bonding andhydrogen bondingAs the strength and magnitude of the intermolecular forces increase, the boiling point increases because it becomes increasingly difficult to break the bonds and requires more energy for the same.Since different types of intermolecular bonding are present, the answer to the question cannot be given in a single sentence.Analyzing all types:If, for large covalent molecules, the intermolecular forces increase, then the boiling point will increase.If only dispersion forces are present, then as the number of electrons increases (and consequently the mass), so will the dispersion forces. Therefore, boiling points will be higher.If only dipole-dipole bonding is present, then, as the molecule increases in size, the charge is dispersed in the molecule, strength of the polarity decreases and thus the intermolecular forces decreases. Therefore, boiling point decreases.If only hydrogen bonding were present, the strength of the bond will depend on the halogen atom with which hydrogen forms a bond. It does not depend on the mass/size of the molecule.However, dipole-dipole and hydrogen bonding can never exist in a substance on their own but with dispersion forces.Therefore, as the mass/size of a covalent molecule increases, the dispersion forces increase and will lead to a higher boiling point independent of hydrogen bonding and the decrease in dipole-dipole bonding will be compensated by an equal or higher increase in dispersion forces.Large covalent molecules do not have low boiling points (in comparison with small covalent molecules). But boiling point of covalent molecules, in general, is less than that of ionic molecules.
Which kind of force is a dipole force?
Intermolecular attraction
