Newton's Law of Cooling states that an object heats or cools at a rate directly proportion to the difference between its current temperature and the temperature of its environment.
This can be written as a differential equation , where denotes time and is constant.
Given a starting temperature of , the solution is .
If you know , and , you can solve for .
