EXPLANATION:

CHEMICAL PROPERTY

  • Chemical properties are any of the properties of matter that can be observed and measured only by performing a chemical change or chemical reaction.

Example:

  • Reactivity with other chemicals
  • Toxicity
  • Coordination number
  • Flammability
  • Enthalpy of formation
  • Heat of combustion
  • Oxidation states
  • Chemical stability
  • Types of chemical bonds that will form

PHYSICAL PROPERTY

  • physical property of matter is a characteristic that can be observed and measured without changing the chemical identity of a substance. Any property that can only be observed after a chemical change occurs is a chemical property, but a physical property can be seen when no change occurs or when a physical change happens. 

Example:

  • Albedo – reflectivity of an object
  • Area – size of a two-dimensional surface
  • Boiling point – temperature at which a liquid changes into a gas
  • Brittleness – tendency to break under stress
  • Color – wavelengths of light reflected by matter
  • Density – amount of matter per unit of volume
  • Ductility – measure of how readily a substance stretches into a wire
  • Malleability – measure of how readily a substance may be pounded or pressed into sheets
  • Freezing point – temperature at which a substance changes from a liquid into a solid
  • Length – longest dimension of an object
  • Luster – measure of the interaction between light and an object’s surface
  • Mass – amount of matter in an object
  • Solubility – amount of matter that dissolves in a solvent
  • Temperature – measure of the thermal energy of a substance
  • Viscosity – resistance to deformation by stress; resistance to flow
  • Volume – three-dimensional space a substance occupies
  • Weight – effect of gravity on a mass
