The solid in bottle melts at 150 degrees C ionic or molecular?
molecular-weak intermolecular forces mean that only a small amount of energy is required t break the bonds.
Does the melting point depend on the substances being melted?
Yes, because the melting point depends on the strength of the intermolecular forces, which are different for different molecules and compounds. Stronger intermolecular forces mean a higher melting point.
When you add heat to a solid does its kinetic energy rise?
Yes the kinetic energy of solid increases resulting in increase of vibration of atoms in their mean positions
Why isn't the bottom part of the earth's mantle molten?
The bottom part of the Earth's mantle is not molten because the extreme pressure at those depths increases the melting point of the rocks and minerals present. This means that even at high temperatures, the pressure prevents them from melting.
An increase in temperature causes a decrease in the amount of gas able to dissolve in a liquid solvent Why does this occur?
As temperature increases the mean kinetic energy of all particles present increase, allowing for the gases dissolved to evaporate more readily, as they are in a greater state of vibratory motion - that is they are present in a more gaseous form. Phase is determined by the extent of motion of particles, which is determined by the intermolecular forces acting between molecules. An increase in temperature will also increase the motion of dissolved particles by weakening the forces acting between the solute and solvent. This allows the dissolved gases to evaporate out of solution. Hence an increase in temperature corresponds to a decrease in the solubility of gases in liquids. Hope it helps. By Vibs

What happens to the intermolecular spaces when some energy is removed from a gas or liquid it decreases it increases it is not affected or increases and decreases alternatively?
By removing energy, what you mean is reducing temperature. A gas or liquid will contract as it gets colder, and intermolecular spaces will decrease.
Why are covalent bonds typically much stronger than intermolecular forces?
Well, a crystal is solid. If you mean, are ionic bonds stronger than covalent bonds, then the answer would be almost always. With a few exceptions, the ionic bond has a greater intermolecular force than a covalent bond. One exception might be a diamond and a weak ionic compound like RbBr.
What is the intermolecular force found in CH5OH?
If you mean CH3OH, then the strongest intermolecular force is hydrogen bonding as this is an alcohol containing and OH group. There are other other forcs such a sLondon dispersion forces but these are weaker as CH3OH doesn't have many electrons.
What does it mean for a substance to be a pure substance?
If a pure substance is volatile it means that it vaporizes readily at room temperature. This also means that the substance has weak intermolecular forces.

What does the WORD intermolecular mean?
Intermolecular describes the interactions between separate molecules.
When you add heat to a solid does its kinetic energy rise?
Yes the kinetic energy of solid increases resulting in increase of vibration of atoms in their mean positions
What does forces between particles mean?
It means when their are movement between the particles like vibration in a solid.
What is a term that mean not being able to be dissolved in a particular substance?
The term that means not able to be dissolved in a particular substance is insoluble. This results from differing intermolecular forces between solute and solvent.
Is hexane a solid liquid or gas?
It has to do with intermolecular forces holding the molecules together. Both ethane and hexane are hydrocarbons, so the only intermolecular forces at work are dispersion forces. There are more/greater dispersion forces in hexane than in ethane because there are more carbon atoms. This stronger force makes it harder for the molecules to became a gas and keeps them as a liquid until heat is applied, then it can vaporize.
