The more solid a substance is, the less kinetic energy there is. This is because there is not a lot of space for the atoms in the solid state to move. However, in the gaseous state, the atoms are far apart with plenty of space, this lets them create a lot more kinetic energy. Solids have a lot more intermolecular forces because the atoms are together. The IMF (intermolecular force) is what lets the atoms/molecules stick together. In the solid state, all the atoms are stuck together with little to no room in between. In the liquid state, it has a lot of IMF but is weaker then the IMF in the solid state. This is why you have so much resistance when you try to move through water. In the gaseous state, there is little to no IMF because the atoms are all so far apart. This makes it easier for everyone to move around.
To answer your question more directly: As the substance is heated to its melting point, there is an increase in kinetic energy, but decrease in intermolecular forces.
