Explain how melting and boiling points are influenced by intermolecular forces

All matter is made up of particles and there are three states of matter that particles can be in: solid, liquid, or gas. We can represent the different states of matter using the simple Particle Model, where particles are represented by small spheres. The melting point is the temperature where melting and freezing occur (the transitions between a solid and a liquid), and boiling point is the temperature at which boiling and condensation occur (the transitions between a liquid and a gas).You have to transfer energy to change between different states, and the amount of energy needed to change state varies depending on the intermolecular forces holding the particles together. Therefore, the stronger the intermolecular forces between the particles, the more energy needed to transition between the different states, and the higher the melting and boiling point.
