SUMMARY
The final temperature of a heated copper ball can be accurately determined using the volume expansion formula rather than linear expansion. The discussion highlights that for a copper ball with a radius of 1.4 cm and a diameter increase of 0.22 mm, the correct approach involves the equation (delta)V = 3*alpha*V*(delta)T. It is crucial to convert measurements to meters and use the radius for calculations to find the change in volume (delta)V accurately.
