what attractive force holds molecules of the same substance together?
Cohesion
Describe the relationship of attraction forces between molecules and the ability of a slovent to dissolve a substance?
when the attractive forces or the lattice enthalpy of the substance increases it will be difficult for the solvent to split and dissolve it.hence solubility decreases
Why do the melting and boiling points of a particular subsatnce vary?
It is because the intermolecular forces(the attractive forces between the molecules of a substance) differ from one substance to another. The chemical with the stronger intermolecular forces will have higher melting and boiling points, and vice versa. This is because more energy is required to separate the molecules to melt or boil the substance, if the forces are strong. The factors that determine the size of these forces are :the type of bonding in the molcules, andthe mass of the molecules.
What is meant by a mole of a substance?
A mole of a substance is 6.022X1023 atoms, molecules, or formula units of a substance.
What is an attraction between molecules of the same substance and why?
Cohesion is the force of attraction between molecules of the same substance which binds the particles together.
what attractive force holds molecules of the same substance together?
Cohesion
In which state of matter are the particles most free to move about?
In the gaseous state of matter, the molecules of a substance are most free to move about as there is little attractive forces between the neighboring molecules.
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.
Describe the relationship of attraction forces between molecules and the ability of a slovent to dissolve a substance?
when the attractive forces or the lattice enthalpy of the substance increases it will be difficult for the solvent to split and dissolve it.hence solubility decreases
What is the smallest part of a substance that has all the porperties of the substance?
Molecules are the smallest part of a substance. Molecules have all the properties of a substance.
Molecules in an object or substance are always in?
Molecules in an object or substance are always in motion.

What the definition of molecules?
Molecules are the smallest particles of a substance.
What is cohesive energy?
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
What substance is a mixture of molecules?
The Type of substance of a molecule would be an element.
What is meant by a mole of a substance?
A mole of a substance is 6.022X1023 atoms, molecules, or formula units of a substance.
When glucose molecules link up what substance do they form?
starch molecules
