When choosing a cup of tea, I can choose a big cup or a small cup. I'm wondering if I get more caffeine with the bigger cup or the same amount of caffeine. (in moles)
My question is: For a given teabag and dunking duration - will I get more caffeine in a bigger cup or the same amount?
- Teabag is placed in cup first - and hot water poured directly onto the bag
- Same amount of stirring across both cups (assume three spoon swirls)
- The main varying parameter is the volume of solvent changing
Question behind the question - trying to express it another way
- Is there a kind of 'fixed rate of dissolution' that limits the amount of caffeine that comes out over a period of time - ie for two cups where one is 250ml and one is 300ml - and each have a tea dissolving time of 30s - wouldn't they have the same number of moles of caffeine at the end because of an upper bound on the rate of caffeine dissolving?
