  • ATOMS OR GROUP ORA GROUP OF TWO OR MORE ATOMS ARE CALLED MOLECULES
  • PRESSURE IS DEFINED AS THE FORCE EXERTED PER UNIT AREA
  • WHAT IS THE BOILING POINTS OF WATER 100C
  • ATNOSPHERIC PRESSURE MAY BE MEASUERD BY BAROMETER
  • THE SI UNIT OF PRESSURE IS PASCAL
  • PLASMA IS AN IONIZED MIXTURE OF POSITIVE IONS AND ELECTRONS
  • FLUID IS A SUBTANCE THAT HAS THE ABILITY TO FLOW.
  • VISCOSITY REFERS TO THE RESISTANCE OF A LIQUID TO FLOW
  • SURFACE TENSION IS DEFINED AS THE PROPERTY OF THE SURFACE OF A LIQUID TO RESIST THE APPLICATION OF FORCE
  • INTERMOLECULAR FORCE BETWEEN LIQUID PARTICLES COHESIVE FORCE
  • ADHESIVE FORCE FORCES BETWEEN DIFFERENT SUBTANCE SUCH AS WATER AND GLASS
  • IS THE CONVEX OR CONCAVE SURFACE OF A COLUMN OF` LIQUID MENISCUS
  • VAPORIZATION IS THE TRANSFORMATION OF LIQUID INTO GAS
  • BOILING IS A TYPE OF VAPORIZATION THAT OCCURS WHEN A LIQUID IS HEATED TO ITS BOILING POINT
  • crystalline solid are the most common type of solids.they have a well-defined shape.
  • atom the smallest particle of an element that can participate in a chemical combination
  • the property of the surface of a liquid that allows it to be compressed without breaking is called viscosity
  • the property of a liquid thatnakes it resist an external force surface tension
  • result from a competion beetwen cohesive force and adhesive force capillary action
  • the process when liquid change to water vapor
  • solid that has no defenite form or structure amorphous solids
  • sublimation is a solid to gas
  • deposition gas to slid
  • vaporization liquid to gas
  • condensation gas to liquid
  • freezing liquid to solid
  • melting solid to liquid
  • isotopes atomic species that have the same atomic number but different mass number
  • state that no two electron in an atom can have the same set of quantum number pauli exclusion principle
  • alsop called orbital angular momentum quantum number ;defines the shape of the orbitals azimuthal quantum number
  • describes the orientation of the electron in space magnetic quantum number
  • tells the orientation of the spin axis of an electron spin quantum number
