Liquid 8 Records

If The Thermometer Was Immersed Below The Surface Of The Liquid (2 Moles Of Glycerol And 8 Moles Of Water) In The Boiling Flask, Would The Temperature Be Greater Or Less Than 100 Degrees Celcius? (vs When The Thermometer Was Immersed Above The Surface Of The Liquid, Therefore Recording Only The Vapor Temperature. And Why Is The Temperature Greater Or Less Than 100 Degrees C?

Any Help Would Be Appreciated! Thanks!
