An object at a temperature of 80?C to be cooled is placed in a refrigerator maintained at 5?C. It has been observed that the rate of temperature change of such an object is proportional to the surface area A and the difference between its temperature T and the temperature of the surrounding medium. Determine the time for the temperature to reach 8?C if the constant of proportionality α = 0.02(s · m2)^-1 and A = 0.2 m².
