Hot-air balloons can rise up into the air because hot air is lighter, allowing it to float up into the sky.
Hot air
Mostly get hot and rise.
yes
Hot air rises. As air is heated, it becomes less dense and therefore more buoyant, causing it to rise. This is due to a difference in temperature creating a temperature gradient, leading to the movement of air.
HOT rises COLD sinks
cause im hot
There are many chemicals found in a hot air balloon to make it rise. The main elements/chemicals are Helium and Hydrogen.
Convection
Hot air rises and cold air falls.
No Gas Just hot air which is why it is called a hot air balloon. If you were wondering hot air is lighter than cold air which makes it rise so when it is trapped inside the balloon the whole thing will rise.
