When a solid changes to a liquid, the particles gain enough kinetic energy to overcome the forces holding them in a fixed position. This causes the particles to break free from their fixed arrangement and move more freely, resulting in a less organized and more fluid arrangement.
The particles are no longer fixed by the forces keeping it a liquid
When temperature increases, particles and molecules gain kinetic energy, causing them to move faster and spread apart, which can lead to changes in state, such as solid to liquid (melting) or liquid to gas (evaporation). Conversely, when temperature decreases, particles lose kinetic energy, move more slowly, and come closer together, which can result in the transition from gas to liquid (condensation) or liquid to solid (freezing). These changes in motion and arrangement affect the physical properties of substances.
When a substance freezes, its particles slow down and come closer together, forming a more structured and rigid arrangement. This results in the substance transitioning from a liquid state to a solid state.
As the ice cube is solid , the particles are tightly packed together but as it melts it changes to a liquid so the particles change so that they are like particles in a liquid. the mass is conserved ( stays the same)
when matter changes state either evolution or absorption of enrgy occurs for example when a solid changes to liquid or a liquid changes to gas energy is absorbed and in case of conversion of gas to liquid or liquid to solid enrgy is liberated....

The average speed of the particles decreases.
The distance between particles increases as a substance changes from a liquid to a gas. In the gas phase, particles are spread far apart and move freely, leading to higher distances between them compared to the closer arrangement in the liquid phase.
The physical property that changes from gas to liquid is the arrangement of particles. In a gas, particles are far apart and have high kinetic energy, moving freely. In a liquid, particles are closer together and have lower kinetic energy, allowing them to flow and take the shape of the container.
As a substance changes from a liquid to a gas, the particles move further apart and gain more kinetic energy, leading to increased randomness and higher speed of movement. In contrast, as a substance changes from a solid to a liquid, the particles gain enough kinetic energy to overcome their fixed positions in a crystal lattice and begin to slide past one another, resulting in a less ordered arrangement and increased freedom of movement.
water changing to a solid: freezing movement of particles: vibration in fixed positions. arrangement: fixed positions (bonds between every particle). moving closer together water as a liquid: movement of particles: move about (slide past each other) arrangement: close together with no regular arrangement water to gas: boiling movement of particles: free/random movement at high speeds. arrangement: particles move further apart with no bonds between particles.

Arrangement of particles determind the phase
the arrangement of particles in a pancake are that when you prepare the pancake with the ingredients it turns into a liquid and then when you cook it change into a solid
During melting, a solid substance changes into its liquid state, with an increase in thermal energy causing the particles to overcome the forces holding them in a fixed position within the solid lattice structure. This results in a break in the orderly arrangement of particles, leading to a more disordered arrangement in the liquid state.

in my opinion, I don't really know
