11. They also strive to characterize the amount and properties of matter and energy shaping the universe. 12. :: Inertia is a property of matter . 13. Innate attractions and repulsions joined size, shape, position and motion as physically irreducible primary properties of matter . 14. :: Mass is an intrinsic property of matter , which doesn't depend on gravity, atleast in classical mechanics. 15. In 1900 he developed a powerful model to explain the thermal, electrical, and optical properties of matter . 16. Condensed matter physics is the field of physics that deals with the macroscopic physical properties of matter . 17. Furthermore, the absorption process is strongly neutron polarization analysis, a technique which probes for magnetic properties of matter . 18. Heat capacity is an extensive property of matter , meaning it is proportional to the size of the system. 19. In 1978, he was a guest scientist in the USA USSR Exchange Program in Fundamental Properties of Matter . 20. In the Solvay Conference of 1930, Cabrera participated with a paper titled " The magnetic properties of matter ."
