Explanation:
Characteristic Properties of Matter—The Key Ideas The physical properties of matter include color, odor, density, solubility, melting point, boiling point, and electrical conductivity. These are properties that can be observed without chemically changing the substance.

Explanation:
Everything around us has mass and volume and they occupy space, and we called them as matter. It can be in four sate, like solid, liquid, gas and plasma. We will talk about main properties of matter in this unit like, mass, volume, density, elasticity, inertia...Etc. You can classify matters with their physical or observable properties and chemical or unobservable properties, for example their smells, colors, shapes give you an idea about it. On the contrary unobservable properties like conductivity of the matter cannot be understood from appearance or smells of the matter.
Mass
Mass is the quantity of the matter in a substance. We show mass with m, and unitsof mass can be gram (g) or kilogram (kg). It is not the distinguishing property but common property of matters, because different matters can have same mass.
Inertia
Inertia is one of the properties of matter. It is the resistance of the matter to change its state of motion. An unbalanced force can only change the state of motion of the matter.
Volume
Volume is the space occupied by the matter. It is also common property of matter and does not help us in distinguishing them. We show it volumewith V and unit used in SI system is m ³.

. Density Density is a property of every substance which is mass per unit volume. Weight Density Weight Density is the weight of the substance per unit volume.
Densities of various substance at atmospheric pressure and room temperature
Specific Gravity Specific gravity of a substance is its density relative to that of water and is a pure number. Specific gravity is also called relative density.
Elasticity Stress is the magnitude of force applied in a body divided by the area over it is exerted. Three Categories: 1. Tensile stress 2. Compressive stress 3. Shear stress
. Hooke’s Law Hooke’s Law states that the amount of deformation experienced by a body under stress is proportional to the magnitude of the force applied to it.
. Elastic Limit and Ultimate Strength
Properties of Materials Ductility is the property of metals which can be deformed beyond the elastic limit. Malleability is the property of metals which has a large plastic range in compression Ductility is the property of metals that has a large plastic range in tension.
Four Methods of Shaping Metals
. Structures of Solids Crystalline is the structure of solids in which atoms are arranged in regular pattern.
Stress Stress is defined as the ratio of applied force over area.
Strain Strain is equal to the ratio between the change in length and the original length.
Modulus of Elasticity Modulus of Elasticity is defined as the ratio between the stress and the strain.
Young’s Modulus For tensile or compressive stresses, the modulus of elasticity is called Young’s Modulus. Young’s modulus depends on the composition of the material.

Shear Shear stresses change the shape of an object on which they act but not on its volume. Angle of shear is the measure of the relative distortion of the block caused by the shear stress.
Shear Modulus Shear Modulus or sometimes referred to as Modulus of Rigidity is the ratio of shear stress to shear strain. The higher the value of shear modulus, the more rigid the material.
Bulk Modulus Bulk Modulus is the ratio of volume stress over the volume strain. Bulk modulus applies to uniform volume compression.
