Physical mineralogy is the specific focus on physical attributes of minerals. Description of physical attributes is the simplest way to identify, classify, and categorize minerals, and they include:
crystal structure
crystal habit
twinning
cleavage
luster
diaphaneity
color
streak
hardness
specific gravity
Shape is not a fundamental mineral property but can be a characteristic of a mineral's crystal form. Minerals exhibit specific crystalline structures that determine their external shape, but these shapes can vary based on growth conditions. Key mineral properties include hardness, luster, color, streak, and cleavage, which are more critical for identification. Therefore, while shape is related to a mineral's structure, it is not typically categorized as a primary property on its own.
An intrinsic property of a material that is not related to its reactivity with other substances is its density. Density is a physical property that describes the amount of mass in a given volume of a material, and is independent of its chemical interactions.
Boiling point is a physical property, as it refers to the temperature at which a substance changes from a liquid to a gas without altering its chemical composition. In contrast, chemical stability and reactivity are related to how a substance behaves in chemical reactions, which involves changes in its chemical structure. Burning point, often referred to as flash point, also pertains to a physical property related to combustion but is more specific to flammability.
Yes, buoyancy is considered a physical property. It is a type of physical property because it is related to the density and weight of the item, which are both physical.
The smell of alcohol is considered a physical property. It is related to the compound's volatility and the way its molecules interact with olfactory receptors in the nose. While the odor can indicate the presence of certain chemical compounds, the smell itself does not involve a change in the chemical structure of the alcohol.
No, the taste of honey being sweet is a chemical property, as it is related to the composition and structure of honey at a molecular level. Physical properties of honey would include its color, density, and viscosity.

Basicity is a chemical property that describes the ability of a substance to accept or donate protons in a chemical reaction. It is related to the chemical structure and composition of a substance rather than its physical characteristics.
a physical change is a change in any physical property of a substance, not in the substance itself
A mineral's ability to split along flat surfaces is called cleavage. Cleavage is a characteristic property of minerals related to their crystal structure and internal arrangement of atoms.
A physical property.
Tensile strength is a physical property that describes the ability of a material to resist breaking under tension. It is not a chemical property, as it is related to the physical behavior of the material when force is applied to it.
It is a physical property.
Shiny metal is a physical property because it can be observed without changing the chemical composition of the metal. It is a characteristic related to how light interacts with the surface of the metal.
An intrinsic property of a material that is not related to its reactivity with other substances is its density. Density is a physical property that describes the amount of mass in a given volume of a material, and is independent of its chemical interactions.
To be shiny is a physical property.
