  1. Unit 1 Topic 3 Kinetic Energy

  2. Watch this! Video What is this called? Words? • What does kinetic mean to you? ki·net·ic/kəˈnetik/ Adjective: Of, relating to, or resulting from motion. (of a work of art) Depending on movement for its effect. Xbox KINECT

  3. What does energy mean to you? • What are some synonyms for ENERGY? en·er·gy/ˈenərjē Noun: The strength and vitality required for sustained physical or mental activity. A feeling of possessing such strength and vitality. Synonyms:power - vigour - vigor - vim - zip - strength - pep

  4. FASTER SLOWEST • The Kinetic Theory states that all matter is in constant motion. • This means that all atoms and molecules are in constant motion in all states of matter. • Gas particles are moving ____________ than liquid particles and solid molecules are moving ____________.

  5. GAS LIQUID SOLID States of matter can be identified by the relative speed of their particles (atoms/ molecules).

  6. Temperature? • How is temperature defined? • a measurement of the average kinetic energy of the molecules in an object or system • As the temperature of a substance increases so does the speed of its particles. This means there is a direct relationship between temperature and molecular motion.

  7. GAS boiling LIQUID melting SOLID States of matter can be identified by the relative speed of their particles (atoms/ molecules). TEMPERATURE MOTION

  8. Kinetic Theory states: Molecules are in constant______. • a. motion c. pattern • scatter d. moles • Kinetic Theory states that there is a direct relationship between temperature and motion of the molecules. This direct relationship means that... • as temperature increases motion increases • c. as temperature increases motion decreases • as temperature decreases motion increases • d. temperature and motion do not matter

  9. In the gaseous state of water, which of the following is true? • Molecules are very far apart and are moving extremely slowly • Molecules are very far apart and moving extremely fast • Molecules are strongly attracted to each other and moving extremely fast • Molecules are very close to each other and moving extremely fast • What is happening at point A on the phase change of water graph below? a. The water is in a liquid state c. The water is in a solid state b. The water is changing from solid to liquid state d. The water is changing from a liquid to a solid.
