Solids, Liquids, and Gases + Changes in State

Which factors determine the state of matter?

Collisions of particles usually change what?

As the motion of the particles slows, the particles move closer, what happened to its attractive force?

A solid is matter that has a definite shape but does not have a definite volume.

The attractive forces between the particles in a solid are strong?

Different particle arrangements will not give materials different properties

A diamond is a crystalline solid with particles arranged in a specific, repeating order.

Amorphous solid is when particles arranged in a specific, repeating order.

A liquid is matter with a definite volume but no definite shape.

Liquids flow but can't take the shape of their containers.

The particle motion in a liquid is slower than the particle motion in a solid.

Molecules at the surface of a liquid have surface tension.

A gas is matter that has definite volume and no definite shape.

Freezing is a process that is the opposite of melting.

To change matter from a solid to a liquid, thermal energy does not need to be added.

Once a solid reaches the melting point, it use more thermal energy for particles to separate their attractive forces and finally then the particles move farther apart and potential energy increases.

The change of state from a gas to a liquid is called evaporation.

Sublimation is the change of state from a solid to a gas without going through the liquid state.

Melting is the change of state of a gas to a solid without going through the liquid state.

Which state of matter does not have a definite shape or volume?
