This physical change is called melting.

When matter is heated, its particles gain energy and move faster, leading to expansion or a change in state (e.g., from solid to liquid). When matter is cooled, its particles lose energy and slow down, leading to contraction or a change in state (e.g., from liquid to solid).
When a solid is heated, it will usually change to the liquid phase. This process is known as melting.
In hot chocolate, the primary phase change occurring is the transition of solid cocoa and sugar particles into a liquid state when heated. As the mixture warms, solid ingredients dissolve, creating a homogeneous liquid. Additionally, if steam forms from the heated liquid, that represents a phase change from liquid to gas.
A solid can change Into a liquid when it is heated Example- when heated solid chocolate, the chocolate changes into a liquid. A liquid Can change into a solid when it is cooled Example - If you leave juice in the freezer , the liquid changes into a solid.
When a solid is heated, it gains energy which causes its particles to vibrate faster. Eventually, this increased vibration overcomes the forces holding the particles in a fixed position, leading to the solid melting and turning into a liquid.
The density generally decreases as a substance transitions from solid to liquid to gas. In the solid state, particles are tightly packed resulting in higher density. When the substance melts into a liquid, the particles become less ordered and the density decreases. As the liquid is further heated to form a gas, the particles are further apart, leading to the lowest density.
The particles in a liguid are bonded (not as strongly as a solid which is why it flows.) when it is heated the particles vibrate and eventually the bonds break and the particles break away. This is evaporation.
When sulfur is heated, it undergoes a phase change from solid to liquid, and then from liquid to gas due to sublimation. Sulphur does not undergo a direct change from solid to gas.
The energy between particles. The particles must be heated so that there is no forces of attraction, therefore the solids particles can loosen into liquid particles and the liquids particles can loosen into gas, the heat energy is used to make the particles move faster
