Question 7: T (t) shows the temperature (°C) of an object at any time of t. Temperature dT the rate of change = k (T - 2T), where the number k is a real number between -3 and -0.5. dt If the temperature of the object is 1000°C at the beginning and 140°C after 2 seconds, the temperature of the object is over time find the change.
