Which step accurately describes how to measure the final burette volume?
locate the bottom of the meniscus and record volume to the nearest 0.01 ml. locate the bottom of the meniscus and record volume to the nearest 0.1 ml.
locate the top of the meniscus and record volume to the nearest 0.01 ml.
locate the top of the meniscus and record volume to the nearest 0.1 ml.

When reading the volumes from a burette you would use the bottom of the meniscus. I think you would record to the nearest 0.01 mL since burettes usually have marks for every 0.1 mL and you can usually record one digit past what the measuring equipment has marked. 
I based this answer on what my professors and TAs have told me to do in lab and may be different for you depending on the type of burette you are using.

I hope this helps.  Let me know if you have any further questions.

The answer should be vaporization
