6. A student does four tasks when setting up the respirometer:

I. Measures the level of fluid in the manometer

II. Opens the three way tap and fixes the apparatus together

III. Leaves the apparatus in the water bath for 15 minutes

IV. Closes the three way tap

  

Which is the correct order of tasks?
