The change from the liquid state to the solid state is called freezing. As the liquid cools, it loses thermal energy. As a result, its particles slow down and come closer together.

What happens to particles when freezing?
Freezing occurs when a liquid is cooled and turns to a solid. Eventually the particles in a liquid stop moving about and settle into a stable arrangement, forming a solid. This is called freezing and occurs at the same temperature as melting.
How does cold affect the speed of particles?
Cooling a liquid decreases the speed of the molecules. A decrease in the speed of the molecules allows the attractions between molecules to bring them a little closer together.
Does freezing increase or decrease movement of particles?
Thermal energy gains and the movement of particles increase. In freezing does the liquid lose or gain thermal energy and does the movement of particles increase or decrease? It loses thermal energy and the movement of particles decreases.
How does temperature affect the speed of particles?
With an increase in temperature, the particles gain kinetic energy and move faster. The actual average speed of the particles depends on their mass as well as the temperature – heavier particles move more slowly than lighter ones at the same temperature.
Why does water freeze faster than other liquids?
Water will freeze faster than liquids with salt or sugar in them. Some liquids freeze faster than others because of viscosity, or thickness of the liquid. Viscosity is the resistance of a liquid to flow. ... Thicker liquids will freeze more slowly and some will not freeze at all.
How is freezing affect some materials?
It simply retards the growth of microorganisms and slows down chemical changes that affect quality or cause food spoilage.
Do particles move slower when cold?
Heating matter causes particles in that matter to speed up; cooling matter causes the particles to slow down.
How does ice make things cold?
As we know, ice is colder than room temperature water. Because ice molecules move slowly and cluster tightly together, they produce a relatively low amount of heat. ... In other words, ice absorbs heat from the water. As the water molecules lose energy, they begin to slow down, and consequently to cool.
What happens when atoms get cold?
An increase in the motion of the atoms competes with the attraction between atoms and causes them to move a little further apart. Cooling a solid decreases the motion of the atoms. A decrease in the motion of the atoms allows the attractions between atoms to bring them a little close together.
When ice melts the particles of ice change into other types of particles?
As ice melts into water, kinetic energy is being added to the particles. This causes them to be 'excited' and they break the bonds that hold them together as a solid, resulting in a change of state: solid -> liquid.
How movement of particles in an object affect the speed of sound?
If a material is more dense because its molecules are larger, it will transmit sound slower. ... It takes more energy to make large molecules vibrate than it does to make smaller molecules vibrate. Thus, sound will travel at a slower rate in the more dense object if they have the same elastic properties.
When it gets colder What happens to the size of solids?
Generally, solids are more dense than liquids because their molecules are closer together. The freezing process compacts the molecules into a smaller space.
What happens to particles when temperature decreases?
As the temperature of a solid, liquid or gas increases, the particles move more rapidly. As the temperature falls, the particles slow down.
When the temperature decreases what happens to the movement of the particles?
If the temperature is increased the particles gain more kinetic energy or vibrate faster. This means that they move faster and take more space. If the temperature is decreased,it is the opposite. Particles move slower, because of less energy.
How does temperature relate to speed of molecules?
The speed of the molecules in a gas is proportional to the temperature and is inversely proportional to molar mass of the gas. In other words, as the temperature of a sample of gas is increased, the molecules speed up and the root mean square molecular speed increases as a result.
