Question
Why does hot air rise upward?
✓

Answer

When air is heated, its particles move faster and spread out, causing the air to become less dense. Less dense air is lighter than the surrounding cooler, denser air. This lighter, hot air then rises because it is more buoyant than the cooler air around it.
