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, determine the temperature in Celsius when t = 30minutes. 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.
