Alekssandra [29.7K]

Physical properties of a substance include, solubility, boiling point, etc.

The correct matching of the physical properties with definition is as follows;

  • Solubility - the ability of a substance to dissolve  in another

  • Boiling point - the temperature at which a liquid  becomes a gas

  • Density - the amount of mass in a given volume

  • Buoyant force - the upward force on an object in a  fluid

  • Conductivity - the ability of a substance to transfer  heat or electricity

Above, all the physical properties have been properly matched with the corresponding definitions.
