Heat’s magic: Watch the balloon expand as the bottle warms up! Learn Science with Neha

When a bottle with a balloon attached is placed in hot water, the air inside the bottle heats up. As the temperature rises, the air molecules move faster and spread out, increasing the pressure inside the bottle. This higher pressure forces the balloon to expand.
Conversely, when the bottle is placed in cold water, the air inside cools down, causing the air molecules to slow down and contract. This decreases the pressure inside the bottle, which causes the balloon to deflate. This demonstrates the principles of thermal expansion and contraction of gases. #subscribe #facts #diy #science #airexpandsonheating #statesofmatter #propertiesofgas #classactivity #iceandwater #easy #learning #concepts
