A bowl of soup at 80° C sits in a 20° C room and cools to 74° C after 1 minute. Using the model for Newton's Law of Cooling T(t) = (ToT)ekt +Ts, where To is the initial temperature of the object and T, is the temperature of the surroundings, write the equation for the temperature of the bowl of soup after t minutes in the room. You will need to determine the value of k using the given information.

Question
A bowl of soup at 80° C sits in a 20° C room and cools to 74° C after 1 minute.
S
Using the model for Newton's Law of Cooling T(t) = (To-Ts)ekt +Ts, where To is the initial
temperature of the object and T', is the temperature of the surroundings, write the equation for the
temperature of the bowl of soup after t minutes in the room. You will need to determine the value of k
using the given information.
