a) Calculate the rms speed of an oxygen gas molecule (O2) at 31.0°C.
b) At the same temperature, which molecule travels faster, O2 or N2?
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 10²³ molecules (Avogadro's number). What is the translational kinetic energy of 12.00mol of an ideal gas at 300.0K?
f) A sealed syringe contains 10 × 10?-??6?m ³of air at 1 × 105Pa. The plunger is pushed until the volume of trapped air is 4 x 10?-??6?m ³. If there is no change in temperature what is the new pressure of the gas?
g) A car tyre contains air at 1.25 × 10???5? 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?
