SUMMARY

Dr. Donald Luttermoser from East Tennessee State University critiques the conventional definitions of the three classical states of matter. He defines solids as having strong resistance to both deformation and compression, liquids as having strong resistance to compression but little resistance to deformation, and gases as having little resistance to both deformation and compression. These definitions provide a clearer understanding of the physical properties of each state of matter.

PREREQUISITES
  • Understanding of classical physics concepts
  • Familiarity with material properties
  • Basic knowledge of states of matter
  • Awareness of deformation and compression principles
NEXT STEPS
  • Research the molecular structure of solids, liquids, and gases
  • Explore the effects of temperature and pressure on state changes
  • Learn about the applications of fluid dynamics in engineering
  • Investigate advanced material properties in condensed matter physics
USEFUL FOR

Students of physics, educators in material science, and professionals in engineering and applied sciences will benefit from this discussion on the definitions and properties of the classical states of matter.

Unfortunately, Luttermoser's definitions of the three classical states of matter are rather unsatisfactory.
A better, and more conventional (informal) one is:
1. Solids-strong resistance to both deformation and compression
2. Liquids-Strong resistance to compression, but little resistance to deformation
3. Gas-little resistance to both deformation&compression
