KINETIC MOLECULAR THEORY OF GAS • What is Kinetic energy? • Energy of motion • Kinetic theory of gases • Assume molecules are point masses (possess mass but no volume) • Constant random motion, collisions are completely elastic • energy can be transferred, but total energy remains the same. • Gas molecules are neither attracted or repulsed
KINETIC MOLECULAR THEORY: PRESSURE • Pressure is created by collisions between molecules and the container.
DISCUSSION QUESTIONS: KINETIC MOLECULAR THEORY • Do all your molecules hit the walls of their container with the same force? Justify your answer based on kinetic molecular theory.
DISCUSSION QUESTIONS: KINETIC MOLECULAR THEORY • How does the frequency and force (respectively) of the collisions of the molecules of a gas with the walls of the container change as the temperature of the gas is decreased? Justify based on kinetic model of gases.
DISCUSSION QUESTIONS KINETIC MOLECULAR THEORY • If you increase the molecular mass, the rms ______. Justify your answer • A) Increases B) Decreases C) stays the same
• Calculate the rms speed of an oxygen gas molecule, O 2, at 29. 0∘C.
• Which of the two lines represents the sample at a higher temperature? • Which of the two lines represents with a higher molecular mass? M 1 M 2
• Explain how each of the below laws follow from kinetic molecular theory. • Boyle's law, (P&V): • Charles's law(V&T)/Gay-Lussac’s(P , T), • Avogadro's law, (n&T) • and Dalton's law (partial pressures)
