  2. 2. WHAT IS MATTER? Anything that occupies SPACE and has MASS. Everything we see around us are MATTER.
  4. 4. A phase is a distinct and homogeneous state of a system with no visible boundary separating it into parts. Conversion between these states is called a phase transition.
  5. 5. SOLIDSA solid is matter in which the molecules are very close together and cannot move around.
  6. 6. LIQUIDSAliquid is matter in which the molecules are close together and move around slowly.
  7. 7. GASES A gas is matter in which the molecules are widely separated, move around freely, and move at high speeds.
  8. 8. Summary of the characteristics of Solid liquidand gas gas liquid solid assumes the assumes the retains a fixedshape and volume shape of the part volume and of its container of the container shape which it occupies compressible not easily not easily compressible compressible flows easily flows easily does not flow easily
  9. 9. ARE THERE ONLY 3 PHASES OFMATTER????4th phase of matter PLASMA5th Phase of matter- BEC or Bose-Einstein Liquid condensate
  10. 10. PLASMA Eventually, given enough heat, the electrons and nucleus become separated and into positively, charged ions and negatively charged electrons. This group or cluster of ions and electrons is known as a plasma. PLASMAparticles are VERY EXCITED PARTICLES.
  11. 11.  Sir William Crookes, an English physicist, identified a fourth state of matter, now called plasma, in 1879.
  12. 12. EXAMPLES OF PLASMAAn aurora is a naturallight display in the sky Modern plasma lampsparticularly in the high are a family of lightlatitude (Arctic and sources that generateAntarctic) regions, light by excitingcaused by the collision of plasma inside a closed aenergetic charged transparent burner orparticles with atoms in bulb using radiothe high altitude frequency (RF) power. PLASMA LAMPatmosphere AURORA BOREALIS
  13. 13. BEC OR BOSE-EINSTEIN LIQUIDCONDENSATE In 1995, two scientists, Eric AllinCornell and Carl Weiman, finally created the condensate Two other scientists, Satyendra Bose and Albert Einstein, had predicted it in the 1920s, but they didnt have the equipment and facilities to make it happen at that time. They are super unexcited and super cold atoms.
  14. 14. HOW CAN PARTICLES BE EXCITED??Remember these pictures
