Welcome to the 5th module! Great to see that you are still with us. 

Have you ever wondered how long you have to wait before the grill in your kitchen has cooled down, so you are able to clean it? Or, if you install double glass instead of single, how much money you can save? Or even how to quantitatively calculate heat loss in many situations? These questions are answered using Newton’s Law of Cooling, and will be discussed in this subsection!
