What happens to the molecules of a compound when it changes state from a liquid to solid?

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).

How does change in phase affect entropy changes in a reaction?
It happens because, even in the same compound, atoms/molecules in different phases have different types of behaviour. For example, unlike solids, liquid and gas molecules can 'flow' around.

What happens with a gas is changed to a liquid

What is the hypothesis describing the behavior of molecules when a substance changes from a gas to a liquid?
The molecules will become closer together when becoming a liquid.
What happens to water when it changes state from a solid to a liquid?
You remove energy from it's solid state; then it returns to a liquid. The H20 molecules move further apart when you go from a solid to a liquid (and even further when it goes to a gas)
What happens to molecules when a substance changes from a liquid to a gas?
they get further apart
What happens to molecules when a substance changes from gas to a liquid?
chang to differ formes
What happens to molecules when a substance changes from liquid to a solid?
They start to get closer together
What happens when a solid a liquid and gas when it changes its state?
Well solid to liquid the heat speeds up the molecules and same for liquid to gas but from liquid to solid the coolant slows the molecules down

What happens to the molecules in a gas as it changes back into a liquid?
trick question it dosent it turn into a liquid and then its done
What happens to the molecules when there is a change in state from liquid to solid?
When a liquid changes to the solid state, the molecules slow down so that they only vibrate in place and can no longer flow like a liquid.
What happens when something changes states from a solid to liquid?
the molecules spread out and become less dense
What happens when liquid solids or gas absorb heat?
the molecules gain or lose energy, the more energy these molecules have the easy it is for them to break the bonds holding them together, thus when you apply enough heat to a substance it changes from a solid to a liquid then from a liquid to a gas.
What happens when a liquid changes into a solid?
What happens with a gas is changed to a liquid
What happens when a substance changes state from a solid or liquid?
This change in the state of matter (liquid to solid) is called freezing.This change in the state of matter (solid to liquid) is called melting.They are physical change, the chemical nature of the molecules is not changed.
