Physical Properties

Physical properties of material includes boiling point, melting point, Colour, density. Mechanical properties of material includes strength, elasticity, plasticity, ductility, malleability,hardness, toughness, resilience, toughness.

There are two types of change in matter: physical change and chemical change. As the names suggest, a physical change affects a substance’s physical properties, and a chemical change affects its chemical properties.

Physical Property of Materials In particular, these properties encompass texture, density, mass, melting and boiling points, and electrical and thermal conductivity. All such physical properties are measurable or observable.

A physical property is a characteristic of a substance that can be observed or measured without changing the identity of the substance. Physical properties include color, density, hardness, and melting and boiling points.

• color (intensive)
• density (intensive)
• volume (extensive)
• mass (extensive)
• boiling point (intensive): the temperature at which a substance boils.
• melting point (intensive): the temperature at which a substance melts.

Types of materials

• Metals. Most metals are strong, hard and shiny materials that can be hammered into different shapes without breaking.
• Plastics. Plastics are materials made from chemicals and are not found in nature.
• Glass. Glass is made by melting sand and other minerals together at very high temperatures.
• Wood.
• Fabrics.

A description of some common mechanical and physical properties will provide information that product designers could consider in selecting materials for a given application.

• Conductivity.
• Corrosion Resistance.
• Density.
• Ductility / Malleability.
• Elasticity / Stiffness.
• Fracture Toughness.
• Hardness.
• Plasticity.

Here are some of the most common mechanical properties that define different types of metal:

• Strength. The measurement of how much load a material can withstand before failure.
• Fatigue Strength.
• Brittleness.
• Stiffness.
• Hardness.
• Toughness.
• Embrittlement.
• Homogeneity.

Mechanical Properties of Soils

• Shear Strength. Shear strength refers to the level of shear stresses a material can resist without fracture.
• Consolidation. Consolidation is the process whereby soil volume decreases under the application of a load.
• Permeability and Seepage.
