  • Physical Property
    A measurable attribute describing a substance's state, observable without altering its chemical structure.
  • Color
    A visual attribute perceived by the eyes, indicating how a substance reflects or emits light.
  • Density
    A ratio of mass to volume, determining whether an object sinks or floats in a liquid.
  • Mass
    A measure of the amount of matter present in a sample, often linked to heaviness.
  • Volume
    The amount of three-dimensional space occupied by a substance or object.
  • Boiling Point
    The specific temperature at which a liquid changes into a gas under standard conditions.
  • Freezing Point
    The temperature at which a liquid transitions into a solid, unique for each substance.
  • Melting Point
    The temperature at broadly defined conditions where a solid becomes a liquid.
  • Hardness
    A material's resistance to deformation or penetration, exemplified by substances like diamond.
  • Softness
    A material's tendency to be easily deformed or broken, opposite of hardness.
  • State
    A physical condition of matter, such as solid, liquid, or gas, determined by temperature and pressure.
  • Observation
    The process of using senses to identify measurable attributes without altering a substance's composition.
