Which physical property shows that a mineral sparkles when it reflects light? Cleavage Hardness Luster Streak color

Luster

Explanation:

Luster is the physical property of minerals showing  how a mineral reflects light. There are two types of  Luster which are

Metallic Luster---Metallic luster are for minerals that look  reflective like that of a polished metal. Examples include gold and copper.

Nonmetallic minerals are minerals that do not look reflective and polished like like metal, Instead their appearance may look waxy, Vitreous, Pearly, Silky o, Resinous , greasy or Adamantine etc. Examples include

Adamantine-- Diamond, Vitreous--quartz,Greasy--opal etc

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
