1. Newton’s Law of Cooling By: Hannah and Jess

2. The Law Newton's Law of Cooling describes the cooling of a warmer object to the cooler temperature of the environment. Newton's Law of Cooling states that the rate of change of the temperature of an object is proportional to the difference between its own temperature and the surrounding temperature

3. Formula T-T s =Ce kt Temperature at time t Surrounding Temperature Rate of Change Time Temperature of hot object at time 0- Surrounding Temp e

4. Example!  A murder victim was found at 9 am.  The temperature of a body was measured at 90.3 ˚F.  An hour later the temperature of the body was 89˚F.  The room temperature was a constant 68˚F.  Figure out what time the murder occurred.
