. A steel ball, initially at 100°C is dropped in a water bath at 25°C. After 5 seconds, the temperature of the steel ball is 75°C. Assuming that the water bath is so vast that there negligible change in its temperature, determine the temperature of the steel ball at any time t. Also, determine the time for the steel ball to be within half a degree of the water bath temperature.
