Question 58-61

 

 

Base your answers to questions 58-61

 

A 200.-milliliter sample of CO2(g) is placed in a sealed, rigid container with a movable piston at 296K and 101.3 kPa.

58. State a change in temperature and a change in pressure of the CO2(g) that would cause it to behave more like an ideal gas.

Answer-->  increase the temperature

decrease the pressure

59.Determine the volume of the sample of CO2(g) if the temperature and pressure are changed to 336K and 152.0 kPa.

Answer-->151 mL    (PV/T=PV/T )

60. State, in terms of BOTH frequency and force of collisions, what would result from decreasing the temperature of the original sample of CO2(g), at constant volume.

Answer-->  Frequency of collisions decreases and force of collisions decreases

61. Compare the mass of the original 200.-milliliter sample of CO2(g) to the mass of the CO2(g) sample when the cylinder is adjusted to a volume of 100. milliliters.
Answer--> mass remains the same....(it was sealed)

F halides
