As the temperature of a liquid substance lowers, the molecules and atoms making up the substance slow down their movement. The also pack closer together, making the substance more rigid, turning it into a solid.

How the arrangement and motion of the particle change when a solid melts a liquid boils a gas condensesa liquid freezes?
When a solid melts to become liquid, or a liquid boils to become a gas, the arrangement of particles gets farther apart and less structured, and the motion of the molecules becomes more random and they move faster. The opposite happens when a gas condenses to become a liquid, or when a liquid freezes to become a solid.
What happens to the molecular motion when heat energy is increased?
It increases.
The tendency of the molecules of a liquid at a given tepmpature to evaporate as a result of radom molecular motion?
diffusion
Which mode is heat transferred in liquid?
Heat in liquid is primarily transferred via convection and conduction. Conduction is a short range force, it arises from the transfer of energy via molecular vibration. Convection is more to do with the motion of the liquid as a whole. Conduction trasmits the heat from molecule to molecule, convection causes motion within the liquid due to hotter parts becoming less dense and rising.
What does Molecular Motion mean?
When the temperature increases during a chemical or physical change the molecular movement increases. This means the molecular movement is faster. If the temperature decreases the molecular movement decreases. This means the molecular movement is slower.
Which state of matter has the least molecular motion?
The solid state has the least molecular motion.

What happens to the solubility of a gas in a liquid if the temperature goes up?
The solubility of a gas in a liquid typically increases as the temperature goes up. This happens because the molecular motion speeds up to aid the reaction.
How molecular motion changes as a substance changes from one state to another?
Molecular motion is less constrained in liquid than in solid and is less constrained in gas than in liquid.
What is the exact molecular motion of liquid?
It is not known and, thanks to Brownian motion, it cannot be known.
What happens to the molecular motion when heat energy is increased?
It increases.
The tendency of the molecules of a liquid at a given tepmpature to evaporate as a result of radom molecular motion?
diffusion
What is the definition of a Convection cell?
The transfer of heat through a fluid (liquid or gas) caused by molecular motion.
What changes would occur at a molecular level if a liquid is placed in cool conditions?
the motion of the molecules would slow down
Molecular motion of a gas?
Solid particles vibrate while locked in place. As they receive more energy, particles speed increases. Once the particles have enough energy they break apart and slide past each other as a liquid. The particles speed continues to increase as energy is added. Finally, they gain enough energy to break free and move independently as a gas.
The direct transfer of molecular motion through solids?
The direct transfer of molecular motion through solids is called conduction
During the process of diffusion what happens?
Diffusion is the movement of molecules from a region of higher concentration to one of lower concentration by random molecular motion.
