Physical Properties Examples
Physical properties are the characteristics of a substance that are called "observable." They are measurable, collectible information about substances that scientists can gather, record, and compare to previous recordings.
There are two kinds of physical properties: intensive properties and extensive properties. Intensive properties aren't dependent on the size or reach of the system. They also don't depend on the amount of the substance being measured. Extensive properties, on the other hand, show an additive relationship that builds with more matter.
Both intensive and extensive properties are usually only true when the amount of the sample and its divided amounts don't affect a physical or chemical process.
1. States of Matter
The boiling point, melting point, and freezing point of a substance would be considered to be a physical property. In addition, the substance's temperature would be a physical property. Also, as these properties don't change depending on the amount of the substance being tested, these would be considered intensive properties.
2. Electricity and Magnetics
There are several electrical characteristics measured in a substance's physical properties, including electric charge, electrical conductivity, electrical field, electrical impedance, dielectric ductility, and electric potential. Substances also have identifiable magnetic fields and magnetic fluxes.
3. Units of Measurement
Some physical properties that can be measured for every substance include the mass, volume, density, area, elasticity, thermal conductivity, radioactive qualities, length, weight, solubility, and concentration. These properties would be considered extensive because the values would change depending on the amount present, with the exception of volume which will remain the same as the mass and volume values are changed.
4. Other Properties
Other unmentioned properties, but by far only a sample of possibilities, include momentum, opacity, permeability, permittivity, physical and electromagnetic absorption, albedo, angular momentum, brittleness, plasticity, capacitance, color, distribution, efficacy, and pressure.
