Does a full kettle take longer to boil than a half full kettle?
Why do you think it takes longer to boil a kettle full of water than to boil just enough to fill the cup? So when heat spreads evenly through water, the larger amount of water would be cooler than the smaller amount of water thus, it would take longer for the larger amount of water to be as hot as the smaller one.
