The matter is one that has volume and mass, ie, occupying an area or space. This matter has two properties:
- Extensive properties: It is based on the mass of a body. For example: inertia, weight and volume.
- Intensive properties: It is not based on the mass, that is, they are invariable. For example: density, pressure, temperature and flavor.
18 Examples of Intensive Properties
- Temperature: It is the heat of a substance. Temperature is measured in degrees Celsius (C), Fahrenheit (F), and Kelvin (k).
- Boiling temperature: Traditionally known as the boiling point. It is the maximum temperature of a substance in a liquid state before it goes completely into a gaseous state. For example: the boiling point of water is 100 Celsius ° C.
- Melting point or melting temperature: It is the total temperature of a substance when it goes from a solid state to a liquid state. As a general rule, the melting point is similar to the freezing point.
- Pressure: It is the physical magnitude that calculates the projection of force in a perpendicular path per unit area. It is usually calculated in pascals.
- Specific volume: Volume is considered to be an extensive property, because it is the volume occupied by each unit of mass of a substance.
- Density: It is the total magnitude of mass in a specific volume. The density of a body is indicated as the ratio of the volume to the mass of a body.
- Color: It describes the appearance that a matter or body has to the human eye. For example: The color of aluminum is silver.
- Taste: In chemical studies, and very rarely work with the taste of a body or substances because most of them are toxic.
- Compressibility: It is the ability of a body to decrease volume when subjected to a specific compression or pressure.
- Refractive index: It is the relationship between the speed of light in empty space and the speed of light in a body from which the index is calculated.
- Surface tension: It is the ability of certain liquids to avoid increasing their surface.
- Elasticity: It is the ability of certain materials to reach their original shape after having been subjected to deformations as a result of the use of an external force.
Extensive property examples
- Weight: It is basically the measure of strength of a body. It is the gravitational force that intervenes on a body or object. For example, the weight of a chair on Earth will have a weight of 5 kilograms while the weight of the same chair on the Moon will be less.
- Mass: It is the resistance of a substance to the change of movement. It is also a property referred to the acceleration of a substance. It is very important not to involve mass with weight.
- Volume: It is the distention of a body in three dimensions. It is a quantity derived from the length. The most commonly used units of volume are cubic centimeters (cm3) and liters.
- Potential energy: The potential energy of a body or substance is considered to be the energy stored under the predominance of a force field, which in many opportunities is electrostatic, gravitational, among others.
- Inertia: It is the property of a body that is in a state of rest or uniform motion.
- Length: In the same way that the volume, the length changes with the quantity of the substance, the length is calculated in a single dimension, while the volume is calculated in three (length, width and depth).
