Newton’s Law of Cooling: _____________________________________________________ _____________________________________________________ _____________________________________________________ _____________________________________________________ _____________________________________________________ _____________________________________________________ _____________________________________________________ 11. Mrs. Kretz loves her pizza! Unfortunately, every time she takes it out of the oven, she burns her tongue because she’s too impatient to wait for it to cool. If only she understood Newton’s Law of Cooling!  We are going to help her. We measure the room temperature to be 72 . The pizza is cooked at 425 . From the moment the pizza comes out of the oven, we wait two minutes and then measure the temperature of the pizza to be 285 . How long after taking the pizza out of the oven should Mrs. Kretz wait for the pizza to reach 100 ? (100 is a safe temperature to eat food.) 7.6 Assignment: Page 519 #3‐37 odd, 54, 57‐59 part b (skip part a). Answer the blog on Newton’s Law of Cooling at www.beansclass.com.
