Question 8 (Should you need a copy of the Periodic Table for this question, you will find one on page 8 of this document.) a) Calculate the mms speed of an

oxygen gas molecule (O₂ at 31.0°C. b) At the same temperature, which molecule travels faster, O₂ or Na? c) Using your answer to question 8b above, calculate how much faster? d) Standard Temperature is defined to be 273.15K. What is the average translational kinetic energy of a single molecule of an ideal gas at Standard Temperature? e) One mole (mol) of any substance consists of 6.022 x 10 molecules (Avogadro's number). What is the translational kinetic energy of 12.00mal of an ideal gas at 300.0K? 1) A sealed syringe contains 10 x 10 m² of air at 1 x 10³Pa. The plunger is pushed until the volume of trapped air is 4 x 10 m². If there is no change in temperature what is the new pressure of the gas? g) A cartyre contains air at 1.25 x 10 Pa when at a temperature of 27°C. Once the car has been running for a while, the temperature of the air in the tyre rises to 42°C. If the volume of the tyre does not change, what is the new pressure of the air in the tyre? 7
