macroscopic properties

Examples of macroscopic properties in the following topics:

• Kinetic Molecular Theory and Gas Laws

  • Kinetic Molecular Theory explains the macroscopic properties of gases and can be used to understand and explain the gas laws.
  • The Kinetic Molecular Theory of Gases comes from observations that scientists made about gases to explain their macroscopic properties.
  • Uses the kinetic theory of gases to explain properties of gases (expandability, compressibility, etc. )

• Ionic vs Covalent Bond Character

  • Though ionic and covalent character represent points along a continuum, these designations are frequently useful in understanding and comparing the macroscopic properties of ionic and covalent compounds.

• Microstates and Entropy

  • The interpretation of entropy is the measure of uncertainty, which remains about a system after its observable macroscopic properties, such as temperature, pressure, and volume, have been taken into account.
  • For a given set of macroscopic variables, the entropy measures the degree to which the probability of the system is spread out over different possible microstates.

• Introduction to Bonding

  • These atomic properties help describe the macroscopic properties of compounds.

• The Kinetic Molecular Theory of Matter

  • The kinetic molecular theory of matter offers a description of the microscopic properties of atoms (or molecules) and their interactions, leading to observable macroscopic properties (such as pressure, volume, temperature).

• Esters

  • Their flexibility and low polarity affects their physical properties on a macroscopic scale; they tend to be less rigid, leading to a lower melting point, and more volatile, leading to a lower boiling point, than the corresponding amides.

• The de Broglie Wavelength

  • Thus it became apparent that light has both wave-like and particle-like properties.
  • Before the acceptance of the de Broglie hypothesis, diffraction was a property that was thought to only be exhibited by waves.
  • Even macroscopic objects like tennis balls have a calculable de Broglie wavelength; however, they would be much too small to observe experimentally, and their wave-like nature is not intuitive to common experience.

• Conformational Enantiomorphism

  • Since a significant proportion of the meso-tartaric acid molecules in a sample will have chiral conformations, the achiral properties of the sample (e.g. optical inactivity) should not be attributed to the symmetry of the Fischer formula.
  • Since enantiomers have equal potential energies, they will be present in equal concentration, thus canceling their macroscopic optical activity and other chiral behavior.

• Physical and Chemical Properties of Matter

  • Both extensive and intensive properties are physical properties, which means they can be measured without changing the substance's chemical identity.
  • Physical properties are properties that can be measured or observed without changing the chemical nature of the substance.
  • Some examples of physical properties are:
  • Remember, the definition of a chemical property is that measuring that property must lead to a change in the substance's chemical structure.
  • Here are several examples of chemical properties:

• Ionic Bonding and Electron Transfer

  • At the macroscopic scale, ionic compounds form lattices, are crystalline solids under normal conditions, and have high melting points.
