The particles move faster. Thermal energy is a measure of kinetic energy of molecules.
When enough heat is added to a solid, the particles gain enough energy to overcome the forces holding them in a fixed position. As a result, the particles move more freely and the solid melts into a liquid.
When a solid dissolves in a solvent, the particles of the solid break apart and disperse evenly throughout the solvent. This process involves the separation of the solvent molecules and the solute particles. The solute particles become surrounded by solvent molecules, forming a homogeneous mixture known as a solution.
Kinetic energy is possessed by virtue of the motion of particles. In solids, particles are tightly packed, so the can not move easily(hence the rigidity). In gases, particles are loosely packed, so they can move more freely(hence its ability to flow). Therefore, KE of particles increases when a solid changes to gas.
The particles spread apart, making the substance less dense. The particles also spread apart to fill more space. Also, the movement of said particles become more active.
When energy is transfered to something which conducts heat, the particles in the solid object start to vibrate. As more energy is transfered to the particles, it spreads across the solid objects particles. The hotter the solid, the more it's particles vibrate.

My best guess is that the particles weaken.

particles harden
When an object gets hotter, the particles within the object gain more energy and start to move faster. This increased movement causes the particles to spread apart, leading to expansion of the object. If the object is a solid, the increased energy may be enough to break the bonds holding the particles together, causing the object to melt and change state.

particles in a solid are packed so close together they can only
it becomes a solid.
they move faster, eventually changing the solid into a liquid
The average speed of the particles decreases.
The molecules in the individual solid particles break free of their regular rigid framework by vibrating more energetically. Eventually the particles of the solid lose their shape and fuse together as a pool of liquid.
