Newton's Law of Cooling

  1. May 12, 2010 #1
    Hi, I have a graph of T-TR vs. Time. These values were given to us for an assignment. However, the question then says using these values, "show" that it obeys Newton's Law of Cooling.

    I can't ask my teacher because it's meant to be done on your own but show means many things to me.

    Does show mean manipulate the equation from the graph to that of Newton's Law of Cooling? Does it mean that I have to substitute values in to see if Newton's Law of Cooling works?

    Could someone provide me with a few ideas? Thanks.

    Draw a suitable graph of the data.
    From the graph, show that the rate of cooling is proportional to the temperature difference. (Which is what Newton's Law would predict in this case.)
