STATES OF MATTER

STATES OF MATTER

• 1. SOLID a form of matter that has a rigid,
  fixed volume and shape. Solids are generally
  arranged with unique symmetrical regularity.
  Solids are tightly held together with little
  space between the molecules (or atoms), they are
  incompressible. Strong electrostatic forces,
  which vary from compound to compound, hold the
  molecules together.

The Solid State

• Ice is only one form of a solid.
• Crystalline solids have ordered uniform
  arrangement of the atoms. Some crystalline
  solids are diamonds, metals, and salts.
• Amorphous solids are disordered and do not break
  cleanly. Some amorphous solids are glass and
  plastics.
• All solids have some molecular motion. All
  solids have vibrational modes of energy.

STATES OF MATTER

• 2. LIQUID a form of matter that has a
  definite volume but no specific shape, it retains
  the shape of its container. It is relatively
  incompressible. The space between particles and
  the strength of the forces holding a liquid
  together is between that of a solid and that of a
  gas.

The Liquid State

• The atoms (or molecules) in the liquid state are
  held together by attractive forces. These forces
  are stronger than those between a gas but less
  than the forces holding a solid together.
• Liquids have both vibrational and rotational
  modes of energy.
• Surface tension, solubility, and capillary action
  are all properties of a liquid which aid in
  distinguishing one liquid from another.

STATES OF MATTER

• 3. GAS a form of matter that has no fixed
  volume or shape, it fills all space available
  irrespective of the container's shape. Gases are
  highly compressible. There is a great deal of
  space between particles and the forces holding
  gas molecules together are very weak

The Gaseous State

• Steam, vapors, mists, and wind are all different
  forms of gases.
• Gas particles are very weakly held together so
  the particles are very far apart.
• Gases have vibrational, rotational, and
  translational modes of energy.
