cup of coffee is made with boiling water at a temperature of 100°C in a room with ambient temperature 20°C. After 4 monites the coffee has cooled to 90°C a. What is the equation T(t) for the temperature of this coffee? b. What is the temperature of coffee after 8 minutes? c. Does the coffee cool more the first 4 minutes or the second 4 minutes? Why does this make sense in term of the differential equation?
