Solution Summary: The author calculates the temperature of the object, T, after t minutes by using Newton's law of Cooling.
To calculate: The model for the temperature of the object, T, after t minutes by using Newton’s law of Cooling where an object is heated to 100∘C and it is left to cool in a room that has a temperature of 30∘C and after 5 minutes, the temperature of the object is 80∘C.
(b)
To determine
To calculate: The temperature of the object after 20 minutes where an object is heated to 100∘C and it is left to cool in a room that has a temperature of 30∘C and after 5 minutes, the temperature of the object is 80∘C.
(c)
To determine
To calculate: The time at which the temperature of the object is 35∘C when an object is heated to 100∘C and it is left to cool in a room that has a temperature of 30∘C and after 5minutes, the temperature of the object is 80∘C.
