Deriving newton's law of cooling
WebJul 14, 2015 · And by Newton's law, it's not a constant. You can solve equation above: T = 65 + 135 e − t / 27. It's exponent, not a linear function (as you assummed). And how you can see from it (or from law directly), if T = 65, d T / d t is zero; if the tea has cooled, it is no longer cool.
