# What are the 3 states of matter by telling their characteristics relating to volume, shape and the particles?

Jul 6, 2017

1. Solid State
2. Liquid State
3. Gas State

See Characteristics Below...

#### Explanation:

Solids (Characteristics)
$\to$ In a solid, particles are packed tightly together so they are unable to move about very much.

$\to$ Particles of a solid have very low kinetic energy.

$\to$ The electrons of each atom are in motion, so the atoms have a small vibration, but they are fixed in their position.

$\to$ Solids have a definite shape.

$\to$ They do not conform to the shape of the container in which they are placed.

$\to$ They also have a definite volume.

$\to$ The particles of a solid are already so tightly packed together that increasing pressure will not compress the solid to a smaller volume.

Liquids (Characteristics)
$\to$ In the liquid phase, the particles of a substance have more kinetic energy than those in a solid.

$\to$ The liquid particles are not held in a regular arrangement, but are still very close to each other so liquids have a definite volume.

$\to$ Liquids, like solids, cannot be compressed.

$\to$ Particles of a liquid have just enough room to flow around each other, so liquids have an indefinite shape.

$\to$ A liquid will change shape to conform to its container.

$\to$ Force is spread evenly throughout the liquid, so when an object is placed in a liquid, the liquid particles are displaced by the object.

Gases (Characteristics)
$\to$ Gas particles have a great deal of space between them and have high kinetic energy.

$\to$ When a gas is put under pressure by reducing the volume of the container, the space between particles is reduced, and the pressure exerted by their collisions increases.

$\to$ If the volume of the container is held constant, but the temperature of the gas increases, then the pressure will also increase.

$\to$ Gas particles have enough kinetic energy to overcome inter-molecular forces that hold solids and liquids together. thus a gas has no definite volume and no definite shape.
