INDIAN GEOGRAPHY

Detailed explanation-1: -Susceptibility to corrosion is not physical properties with respect to the minerals.

Detailed explanation-2: -Color, phase, odor and boiling point are the physical properties. Reactivity with oxygen depends on the chemical nature of object, thus, it is not a physical property. It is a chemical property.

Detailed explanation-3: -Most minerals can be characterized and classified by their unique physical properties: hardness, luster, color, streak, specific gravity, cleavage, fracture, and tenacity.

Detailed explanation-4: -The physical properties of minerals are determined by the atomic structure and crystal chemistry of the minerals. The most common physical properties are crystal form, color, hardness, cleavage, and specific gravity. One of the best ways to identify a mineral is by examining its crystal form (external shape).

Detailed explanation-5: -We will first discuss each of the physical properties that can be used, then develop a methodical approach to the identification of minerals using these physical properties. Among the properties we will discuss are: crystal habit, cleavage, hardness, density, luster, streak, color, tenacity, magnetism, and taste.
