What happens to the molecules of a substance as it moves from liquid state to solid state?

The molecules of the substance lose energy and usually assume a fixed lattice shape (which may be a crystalline form or an allotropic form, dependent on temperature and pressure). Some compounds such as glass (various silica compounds) can transition to an amorphous solid (non-crystalline phase) that can be fractured, but also may very slowly flow above a particular temperature (vitrification).

β 12y agoas its turning to a liquid to a solid, it turns to a gas and the molucules stay together for a solid and a liquid molucules spread apart. now, THATS RIGHT

What happens when a light ray moves from one substance to another?
The speed changes. (and sometimes the angle.)
What is a substance in which a wave moves?
A medium
How fast do molecules move in hot water?
Very fast. It moves faster than cold water, definitely. As the temperature of almost any substance increases, so does its kinetic energy of each molecule.
Do molecules move faster in a gas or a solid?
Basically, a solid is quite stationary. It doesn't move very much. Liquids have more energy, meaning that the particles move a lot freer. In a gas the particles are a lot further apart, meaning that they have a LOT more space to move. Solids can be made to move faster if you give it enough energy (ie, heat). The atoms then start vibrating faster, making spaces between the atoms. This is what happens (basically) when you melt something.
How does conduction work?
In this context we will assume you are referring to thermal conductivity. Thermal conductivity is the macroscopic effect of molecules in a substance colliding with or otherwise coming close enough to other molecules in a substance to impart some of their kinetic energy (translational, vibrational or rotational) to the other molecules. Molecules close to the higher temperature surface (heat source) collide with it and pick up some of the energy of the molecules there. As they bounce away, they collide with other molecules further away and give up some of their energy to the other molecules because they have more energy than the other "cooler" molecules. This process propagates through the substance with the net effect that heat is "conducted" from the heat source to the heat sink. In conduction, each molecule stays pretty much in the same general region during the entire process, just rattling around within its home area. This differs from convection where there is a bulk movement of gas or liquid from one place to another. In the case of convection - a mass of fluid (gas or liquid) moves from an area of one temperature to an area of a different temperature, like the blobs of wax in a lava lamp. Once it gets to a new area, it imparts its energy to (or absorbs energy from) the new surrounding fluid by way of conduction.

What occurs when a substance moves from liquid to gas?
This change of phase is called vaporization and is a physical phenomenon; the chemical nature of the molecules was not changed.
How is viscosity afected by temperature?
viscosity is roughly defined as how fast a liquid moves. temperature affects this level on a molecular level. when something is brought below its freezing point, it turns to a solid, meaning its atoms come as close together as possible. raise the temperature, and it becomes a liquid, meaning the atoms bounce freely, but are still held together. raise it even more, and the substance becomes a gas, and will dissipate. viscosity measures the liquid state. when a substance is near freezing, its molecules move very slowly, and the substance also moves more slowly. if you heat it to near boiling, the opposite happens, the molecules move faster, and are 'more loose', and the substance 'moves faster.'
What substance collects an moves the greatest amount of sediment?
Liquid water.
Which is the only landform that moves?
a glacier or some form of a liquid substance
What happens to the particles of a liquid as the liquid evaporatΔs?
it moves much much faster
What happens when light moves from solid to liquid?
kill
What is the difference between condensation and boiling?
Boiling : the temperature increases substance changes its form from liquid to gas atoms of the substance moves with the high kinetic energy by absorbing heat Condensing : the temperature decreases substance changes its form from gas to liquid atoms of the substance loses atomic kinetic energy by losing heat
When you heat a solid and it melts becomes a?
It becomes a liquid. solid, liquid, and gas are relative terms defining the movement of molecules, solid moves slow, liquid faster, and gas the fastest. molecules move constantly.
What happens to the molecules in a sovelent when it heats up?
They speed up and moves faster and faster.
What happens when a light ray moves from one substance to another?
The speed changes. (and sometimes the angle.)
