This video shows an activity which uses pennies to model the process of radioactive decay. The changing ratio of parent and daughter nuclei observed in samples such as rocks and fossils allows the age of materials to be determined using a technique called radiometric dating.

![🧪Joule-Thomson Effect [an endothermic process]](https://i.ytimg.com/vi/mfDsJJVMXds/mqdefault.jpg "🧪Joule-Thomson Effect [an endothermic process]
In this video, we explore the fascinating phenomenon of Joule-Thomson cooling that occurs when baking soda and vinegar react to produce carbon dioxide. Joule-Thomson cooling is a process in which a gas cools as it expands against a pressure difference. When baking soda and vinegar react, they release carbon dioxide gas, which expands rapidly and cools down. This reaction can be used to demonstrate the principles of thermodynamics and the Joule-Thomson effect in a simple and fun way.
We will begin by showing you the materials needed to conduct this experiment, including baking soda, vinegar, a plastic bottle, and a temporal scanner. Then, we will walk you through the step-by-step process of mixing the baking soda and vinegar producing carbon dioxide gas. The expansion of the gas causes the temperature to drop!
This video is perfect for science enthusiasts, students, and anyone curious about the fascinating world of thermodynamics. So sit back, relax, and join us on this cool scientific journey!
