Question 54

Liquid oxygen boils at 90 K90\text{ K}90 K.

a.

Convert 90 K90\text{ K}90 K to a temperature in ∘C{}^\circ\text{C}∘C.

[2]
b.

Liquid oxygen boils to form gaseous oxygen. State two ways in which the arrangement and motion of the oxygen molecules change as the liquid transitions into a gas.

[2]
c.

The average kinetic energy of the molecules in an ideal gas depends on its temperature. Sketch a graph to show this relationship, clearly labelling both axes.

[2]
d.

A student sets up the apparatus shown below to investigate how the volume of a trapped sample of dry air varies with temperature at a constant pressure.

Charles's Law Capillary Tube Apparatus

Describe how this apparatus can be set up and used to investigate how the volume of the trapped air column varies with temperature. In your description, you should:

  • identify any additional measuring instruments needed
  • explain how the temperature of the air is varied and measured
  • explain how the volume of the trapped air is determined
  • state how the results can be analysed to show the relationship.
