  4. Chapter 7 Lesson 1Law vs. Theory: Pg 263 • Laws • Theories

  5. Chapter 7 Lesson 1:Kinetic Energy and Temperature • Temperature is a measure of the average kinetic energy of molecules

  6. 7-1 Energy and Bonds between Particlesphase changes from liquid to gas • Evaporation and Condensation • Add energy to water = ____________ bonds between molecules • Remove energy from vapor = ___________ bonds between molecules • Liquid Nitrogen or Oxygen • Add energy to liquid nitrogen = ____________ bonds between molecules • Remove energy nitrogen gas = ___________ bonds between molecules

  7. 7-1 Pressure and Temperature: Introduction to the idea of a gas law “See Saw” • What happens if we increase temp in a sealed container? • Gasoline can in summer • Balloon in coldP = T

  8. 7-1 Kinetic Theory • Gases have enough energy to break all bonds between particles • Particles are in constant motion • Move randomly • Collisions are elastic
