In warm air, the gas inside the balloon expands, which causes the balloon to become larger. Conversely, in cold air, the gas contracts, making the balloon smaller. This phenomenon is explained by Charles’s Law, which states that when the temperature of a gas increases, its volume (or size) increases as well.

You have made a good point and validation of one of the fundamental laws of thermodynamics and that is a very good observation from your end. Good job.
Great job demonstrating Charles’ Law with clear measurements and multiple trials! Your data clearly shows how temperature affects gas volume, and your graph helps make the trend easy to understand. You showed strong scientific thinking by identifying variables and testing several temperatures. Keep exploring chemistry concepts. You are building great experimental skills!
