Why does a helium balloon lose its gas much faster than a balloon filled with ordinary air? 🎈 In this video, we explore the science behind "diffusion and Graham’s Law" to understand why helium escapes through the tiny gaps in a balloon much faster than the gases in the air we breathe. Helium has a molar mass of just 4 g/mol, while the average molar mass of air is around 29 g/mol. This huge difference means helium molecules move much faster and diffuse through the balloon more rapidly. So, where does all that helium go? And why does the balloon eventually shrink?
