After heating up in a teapot, a cup of hot water is poured at a temperature of 210°F. The cup sits to cool in a room at a temperature of 71°F. Newton's Law
of Cooling explains that the temperature of the cup of water will decrease
proportionally to the difference between the temperature of the water and the
temperature of the room, as given by the formula below:
T=Ta +(T. – Tq)e-kt
T. = the temperature surrounding the object
ТО = the initial temperature of the object
t=the time in minutes
T = the temperature of the object after t minutes
k=decay constant
