What happens as a solid begins to change to a liquid?
The internal energy of the item increases, and the molecules become less ordered.
What happens to movement and position of molecules when they change from a liquid to a solid?
When molecules change from a liquid to a solid, they lose energy and begin to move more slowly. As the temperature decreases, the molecules arrange themselves into a more ordered and fixed structure, resulting in a solid state. This transition reduces the freedom of movement significantly, causing the molecules to vibrate in place rather than move freely as they do in a liquid.
What happens to snow molecules during phase change?
During a phase change from solid snow to liquid water, the snow molecules absorb heat energy and gain enough kinetic energy to break their bonds and transition into liquid form. This process is called melting.
When a solid dissolves in a liquid it seems to disappear into it. how is it possible?
The solid separates down to the molecular level - and they mix with the water molecules. We cannot see molecules with the naked eye !
Is solid ice melting to a liquid a physical or chemical change?
Melting solid ice into liquid water is a physical change. It involves a phase change from solid to liquid without altering the chemical composition of water molecules.
What happens to molecules when they change from one state of matter to another?
the denseness of the molecules change(compact=solid, really far=gas, in the middle=liquid)

When a substance changes from a solid to a liquid what occurs?
This change in the state of matter (liquid to solid) is called freezing; it is a physical change, the chemical nature of the molecules is not changed.
What happens to snow molecules during phase change?
During a phase change from solid snow to liquid water, the snow molecules absorb heat energy and gain enough kinetic energy to break their bonds and transition into liquid form. This process is called melting.
When solid is heated and melts into a liquid what happens to its molecules?
they get farther apart.
What happens to the molecules of a substance as it moves from a liquid to a solid?

What happens to molecules when a substance changes from liquid to a solid?
They start to get closer together
When the molecules in a body move with increased speed it is possible that the body will change from what to what?
As the molecules in a body move with increased speed, i.e. increasing kinetic energy, it is possible that the body will change from the solid phase to the liquid phase, or the liquid phase to the gas phase, and in some cases from the solid directly to the gas phase.
What happens to a substance as it under goes a phase change?
A change from gas to liquid, from solid to liquid, from liquid to gas, etc.
When a solid dissolves in a liquid it seems to disappear into it. how is it possible?
The solid separates down to the molecular level - and they mix with the water molecules. We cannot see molecules with the naked eye !
