MODEL 2: THE IDEAL GAS LAW Gases demonstrate all of the following properties V x 17p VT Boyle's Law Charles's law Avogadro's Law CRITICAL THINKING QUESTIONS GUM OV which of the following incorporates all the gas behavior observed VONTP V." V Decall that yox is the same thing as y e x in which is a proportionality constant Rewrite the correct expression from CTQ5 with an equals sign, using the symbol Ras the proportionality constant. 7. Starting with your expression in CTQ6, multiply both sides by anything appearing in the denominator, resulting in an expression with no denominator. 8. The proportionality constant, R, is called the ideal gas constant and is known to have a value 0.0821 L'atm/k-mol. Of the variables pressure, volume, number of moles, and temperature, how many would you have to know to calculate them all? 9. Solve the ideal gas equation, PV = nRT, for each of the following. (Do not memorize all of these.) P = TE NE Vs 10. Charles's law states that the volume is directly proportional to the temperature for a given amount of gas at a particular pressure. Explain how this is consistent with the ideal gas equation. you are using the gas constant in CTQ 8. what units must you use for ? For P2 Form 12. Standard temperature and pressure is defined as 0 °C (273 k) and 1 atm. What is the volume of one mole of gas under these conditions? 136 Copyright © 2015 Pearson Education, Inc.
