Reaction of 3-methyl-3-pentanol heated with sulfuric acid gives what products?

I was told to write an equation, using bond-line formulas, for the reaction expected when 3-methyl-3-pentanol is heated with sulfuric acid. Give the IUPAC names of all products. What differences in experimental procedure would need to be varied in order to do the reaction with 3-methyl-3-pentanol as opposed to 2-methyl-2-butanol. I understand when we do the dehydration using H2SO4 which acts as a strong acid, theres a creation of a double bond when the original substances loses a hydrogen and 'dehydrates', what I don't understand is how we are able to predict what the exact products will be. Thanks
