Exploring The Effects Of Temperature On Gas Volume Through Charles's Law

Dr. D demonstrates Charles's Law using liquid nitrogen and balloons. The video explains how the volume of a gas is related to its temperature, showcasing this with a practical experiment. Liquid nitrogen is used to cool balloons, causing them to shrink, and then they return to their original size when warmed. The video concludes with a fun experiment involving multiple balloons.
