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.
The snow (solid) become water (liquid); the distances between molecules are decreased during the change of phase.
molecules of a solid break up get's into the space that is in between the liquid molecules
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
The internal energy of the item increases, and the molecules become less ordered.
The solid separates down to the molecular level - and they mix with the water molecules. We cannot see molecules with the naked eye !
the denseness of the molecules change(compact=solid, really far=gas, in the middle=liquid)
The snow (solid) become water (liquid); the distances between molecules are decreased during the change of phase.
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.
