Properties of Matter Quiz

Definition of Matter

• Matter is anything that has mass and takes up space.
• It is a physical substance that has inertia and can occupy a specific location.

Properties of Matter

• Physical Properties: characteristics that can be observed or measured without changing the composition of the matter.
  • Examples: color, shape, size, texture, density, and phase (solid, liquid, or gas).
• Chemical Properties: characteristics that describe the way a substance interacts with other substances.
  • Examples: reactivity, flammability, and ability to conduct electricity.

States of Matter

• Solid: particles are closely packed and have a fixed shape and volume.
• Liquid: particles are close together but can move past each other, taking the shape of their container.
• Gas: particles are widely spaced and can move freely, expanding to fill their container.
• Plasma: a high-energy state where particles are ionized, often found in stars and lightning.

Classification of Matter

• Elements: substances consisting of only one type of atom.
• Compounds: substances consisting of two or more different elements chemically bonded together.
• Mixtures: combinations of two or more substances that are not chemically bonded.
  • Homogeneous Mixtures: uniform composition throughout, such as air or sugar water.
  • Heterogeneous Mixtures: non-uniform composition, such as sand and water.

Changes in Matter

• Physical Changes: changes in form or state, but not in composition.
  • Examples: melting, freezing, evaporation, and condensation.
• Chemical Changes: changes in composition, resulting in a new substance.
  • Examples: combustion, rusting, and digestion.
