19. circle which of the following depend on the amount of matter present: mass density volume color boiling point

             Mass

Explanation:

Physical properties of substance are classified as Intensive property and Extensive property.

Intensive Property:

                              A physical property whose value is independent of the mass of a substance for which it is measured.

Examples:

                                             i) Melting / Boiling Points

                                             ii) Temperature

                                             iii)  Color

                                              iv) Density

                                              v) Pressure

Extensive Property:

                              A physical property whose value is dependent on the mass of a substance for which it is measured.

Examples:

                                             i) Amount of Substance

                                             ii) Mass

                                              iii)  Volume

                                              iv) Enthalpy
