Mass of an object

A measure of the amount of matter in an object.

Liquid properties

Liquids have a definite mass, but take the shape of their container.

Gas vs Solid

Gases move freely and spread out, while solids have a definite shape.

States of Matter

Matter exists in solid, liquid, and gas forms, each with unique characteristics.

Study Notes

States of Matter

  • Matter is anything that occupies space and has mass.
  • There are three primary states of matter: solid, liquid, and gas.

Properties of Matter

  • Properties used to identify the state of matter include:
    • Shape: Relates to the form an object takes.
    • Mass: The amount of matter in an object.
    • Volume: The space occupied by the matter.

Solids

  • Solids have a definite shape, mass, and volume.
  • Atoms in solids are tightly packed, giving them a fixed structure.
  • Example of solids includes trees, furniture (chairs), and ice.

Liquids

  • Liquids have a definite mass and volume but do not have a fixed shape.
  • The atoms in liquids are close together but can move around, allowing liquids to flow and take the shape of their container.
  • Common examples include milk and juice.

Gases

  • Gases lack a definite shape and volume, taking both the shape and volume of their containers.
  • Atoms in gases are much farther apart, allowing them to move freely and spread out.
  • Everyday examples include the air we breathe, which contains gases like oxygen and helium.

Water's Changing States

  • Water can exist in all three states: solid (ice), liquid (water), and gas (water vapor).
  • The transition from ice to water is called melting, while water vapor is produced through evaporation.

Observations in Everyday Life

  • Matter can be identified in various forms around us; for example, solid, liquid, and gas can often be found in a typical household setting.
  • A simple experiment can show the states of matter by observing the melting of ice to water and then evaporation to water vapor.
