Properties of Matter Quiz

Definition of Matter

• Matter is anything that has mass and occupies space.
• It is the physical substance that makes up all objects, living and non-living.

Properties of Matter

• Physical Properties:
  • Mass: the amount of matter in an object
  • Volume: the amount of space occupied by an object
  • Density: the mass of an object per unit volume
  • State: solid, liquid, or gas
• Chemical Properties:
  • Reactivity: the ability of an object to undergo chemical changes
  • Composition: the type and amount of substances that make up an object

Types of Matter

• Elements: substances made up of only one type of atom
  • Examples: hydrogen (H), oxygen (O), carbon (C)
• Compounds: substances made up of two or more different elements
  • Examples: water (H2O), carbon dioxide (CO2)
• Mixtures: combinations of two or more substances that are not chemically combined
  • Examples: air (oxygen, nitrogen, etc.), soil (sand, clay, etc.)

States of Matter

• Solids:
  • Have a fixed shape and volume
  • Particles are closely packed and have a fixed position
• Liquids:
  • Take the shape of their container
  • Particles are close together but can move past each other
• Gases:
  • Take the shape and volume of their container
  • Particles are widely spaced and can move freely

Changes of State

• Melting: the change from a solid to a liquid
• Freezing: the change from a liquid to a solid
• Evaporation: the change from a liquid to a gas
• Condensation: the change from a gas to a liquid

Properties of Matter

• Mass is the amount of matter in an object.
• Volume is the amount of space occupied by an object.
• Density is the mass of an object per unit volume.
• State refers to whether an object is solid, liquid, or gas.
• Reactivity is the ability of an object to undergo chemical changes.
• Composition refers to the type and amount of substances that make up an object.

Types of Matter

• Elements are substances made up of only one type of atom, for example, hydrogen (H), oxygen (O), and carbon (C).
• Compounds are substances made up of two or more different elements, for example, water (H2O) and carbon dioxide (CO2).
• Mixtures are combinations of two or more substances that are not chemically combined, for example, air (oxygen, nitrogen, etc.) and soil (sand, clay, etc.).
