physical property

Examples of physical property in the following topics:

• Physical and Chemical Properties of Matter

  • All properties of matter are either extensive or intensive and either physical or chemical.
  • For example, the freezing point of a substance is a physical property: when water freezes, it's still water (H2O)—it's just in a different physical state.
  • Physical properties are properties that can be measured or observed without changing the chemical nature of the substance.
  • Some examples of physical properties are:
  • Mass and volume are both examples of extensive physical properties.

• Mass

  • Mass is a physical property of matter that depends on size and shape of matter, and is expressed as kilograms by the SI system.
  • All elements have physical properties whose values can help describe an elements physical state.
  • Physical properties do not change the chemical nature of matter.
  • The physical property we are covering in this atom is called mass.
  • Mass is an intrinsic property that never changes.

• Physical Properties of Covalent Molecules

  • The covalent bonding model helps predict many of the physical properties of compounds.
  • The Lewis bonding theory can explain many properties of compounds.
  • Several physical properties of molecules/compounds are related to the presence of covalent bonds:
  • Covalent compounds generally have low boiling and melting points, and are found in all three physical states at room temperature.
  • Therefore, while the covalent bonding model accounts for many physical observations, it does have its limitations.

• Variation of Physical Properties Within a Group

  • The physical properties (notably, melting and boiling points) of the elements in a given group vary as you move down the table.
  • Each element within a group has similar physical or chemical properties because of its atom's outermost electron shell (most chemical properties are dominated by the orbital location of the outermost electron).
  • A physical property of a pure substance can be defined as anything that can be observed without the identity of the substance changing.
  • Physical properties include such things as:
  • Describe the general trends of physical properties within a group on the periodic table.

• Physical Properties of Carboxylic Acids

  • The following table lists a few examples of these properties for some similar sized polar compounds (the non-polar hydrocarbon hexane is provided for comparison).

• Digital Media and Intellectual Property Issues

  • In addition to protecting the financial incentives of intellectual property, the WIPO treaty and several related international agreements are based on the premise that protecting intellectual property rights is essential to maintaining economic growth.
  • Copyleft and free software activists have criticized the implied analogy of digital property with physical property such as land or cars.
  • They argue such an analogy fails because physical property is generally rivalrous, while intellectual works are non-rivalrous (that is, if one makes a copy of a work, the enjoyment of the copy does not prevent enjoyment of the original).
  • Some libertarian critics of intellectual property have argued that allowing property rights in ideas and information creates artificial scarcity and infringes on the right to own tangible property.
  • Examine how digital media and computer network technologies have reshaped intellectual property issues

• Physical and Chemical Changes to Matter

  • There are two types of change in matter: physical change and chemical change.
  • 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.
  • They are also physical changes because they do not change the nature of the substance.
  • The formation of gas bubbles is often the result of a chemical change (except in the case of boiling, which is a physical change).

• A Physical Aside: Einstein coefficients

  • The Einstein coefficients seem to say something magical about the properties of atoms, electrons and photons.

• Property

  • Property refers to the sum total of one's possessions, as well as their regular income.
  • Private property is the ownership, control, employment, ability to dispose of, and bequeath land, capital, and other forms of property by persons and privately owned firms.
  • Private property is distinguishable from public property and collective property, which refers to assets owned by a state, community, or government rather than by individuals or a business entity.
  • The concept of property is not equivalent to that of possession.
  • Property and ownership refer to a socially constructed circumstance conferred upon individuals or collective entities by the state, whereas possession is a physical phenomenon.

• Physics and Other Fields

  • Most branches of engineering are applied physics.
  • Physics has many applications in the biological sciences.
  • On the microscopic level, it helps describe the properties of cell walls and cell membranes.
  • It might seem that the distinction between physics and biology would be clearer, since physics seems to deal with inanimate objects.
  • What differentiates physics from biology is that many of the scientific theories that describe living things ultimately result from the fundamental laws of physics, but cannot be rigorously derived from physical principles.
