Calculate a Building's Age Using Nickel-63 Decay
Want To Learn More? To watch the entire video and ALL of the videos in the series:
The scenario involves an archaeologist analyzing iron in an old building containing nickel-63, which has a known half-life of 92 years. With only 0.78% of the original nickel-63 remaining, the goal is to estimate the year when this discovery was made. We delve into the calculations and principles of first-order decay reactions.
Understanding Average Speed in Kinetic Molecular Theory
