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

7-1 Energy and Bonds between Particles phase 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

7-1 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 cold P = T

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