SteveAs particles change state from solid to liquid, they gain energy that allows them to overcome the forces holding them in a fixed position. In a solid, particles are tightly packed and vibrate in fixed positions. As heat is added to the system, particles in the solid gain enough energy to break free of their fixed positions and move more freely, resulting in the transition to a liquid state.

Which change of state do particles become less organized?
Particles become less organized when they change state from a solid to a liquid. In a solid, particles are arranged in a specific pattern and vibrate in place, but in a liquid, the particles have more freedom to move around and do not have a fixed position.
What happens when a substance changes state from a solid or liquid?
When a substance changes state from a solid to a liquid, it undergoes melting where it gains enough energy to break the bonds holding its particles together. When it changes from a liquid to a gas, it undergoes vaporization where it gains enough energy to overcome the forces of attraction between its particles.
Do change of state make cooling causes particles to get closer together and materials?
Yes, during a change of state such as from a gas to a liquid or a liquid to a solid, cooling causes particles to come closer together and form more ordered structures. In a gas, the particles are more spread out and have higher kinetic energy compared to a liquid or solid where particles are closer together and have lower kinetic energy.
What is the phase change from a solid to a liquid?
The phase change from a solid to a liquid is called melting. This process occurs when a solid substance absorbs enough heat energy to break the bonds holding its particles together, resulting in the particles becoming more loosely packed and transitioning into a liquid state.
What force has to be overcome in order to change a solid into a liquid?
The force that has to be overcome is the intermolecular forces holding the solid particles in place. As heat is applied, these forces weaken, allowing the particles to move more freely and change from a solid to a liquid state.
