Hot Air Expands at Rachael Sattler blog

Hot Air Expands. In other words, hot air (or warm air) rises up. Hot air expands and spreads out and it becomes lighter than cool air. Air is made up of molecules that are constantly in motion. The hot air expands and increases in volume. The expansion due to heat is called thermal expansion. The density of the air decreases, and it floats upwards, rising through the chimney. As the molecules heat and move faster, they are moving apart. We will now describe an activity to show that hot air is lighter (less dense) than cold air and, being lighter, hot air rises upwards. When you put the bottle with the balloon into the first jar, the hot water heats up the air in the bottle and makes it expand. Cooler air is sucked in through the other chimney to. Now, when air gets heated at a place, it expands, becomes lighter and rises up in the sky. So air, like most other substances, expands when heated and. When a balloon is full of hot air it rises up because the hot air expands inside the balloon. Hot air, therefore, tends to occupy a large volume, and it becomes less dense. As air warms up, the molecules start to vibrate and bump into each.
