An object was left in a room of unknown surrounding temperature. The temperature of the object was
summarized below with respect to the time t (in minutes) the object was initially observed. Predict and
complete the information, i.e. determine the temperature in Celsius when t= 30 minutes. Put your answer
accurate up to four decimal places.
When t= 0, the temperature of the object is 30 degrees Celsius.
• When t= 10 minutes, the temperature of the object is 32 degrees Celsius.
• When t= 20 minutes, the temperature of the object is 33.6 degrees Celsius.
• When t= 30 minutes, the temperature of the object is unknown.
Assume the system obeys Newton's Law of Cooling and the surrounding temperature of the room did not
change.
