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).
There are a few things that happen to a molecule when a solid changes to liquid. The molecules move faster.
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
The molecules will become closer together when becoming 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)
When ice cools it shrinks
they get further apart
chang to differ formes
They start to get closer together
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

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.
trick question it dosent it turn into a liquid and then its done
the molecules spread out and become less dense
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.
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.
