Which property of a mineral sample does not influence how quickly it settles in water? 1) density 2) hardness 3) shape 4) size
satela [25.4K]
<h3><u>Answer</u>;</h3>

4) size

<h3><u>Explanation</u>;</h3>
  • The mineral’s physical properties are used in identifying minerals and are determined by its chemical composition and crystal structure.
  • <u>Streak</u> is the color of the mineral in powdered form and since it is a more accurate illustration of the mineral’s color, its is a more reliable property of minerals than color for identification.
  • <u>Hardness</u> is one of the better properties of minerals to use for identifying a mineral. Hardness is a measure of the mineral’s resistance to scratching.
  • <u>Density</u> may be used to identify minerals. It is used to describe the amount of matter in a certain amount of space. Substances that have more matter packed into a given space have higher densities.
