Hot air generally rises because it is less dense than cold air. As air heats up, its molecules move faster and spread out, making the air less dense and causing it to rise above cooler, denser air. This movement creates convection currents, where hot air rises and cooler air sinks, leading to the circulation of air in the atmosphere.
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.
Cold air is denser than hot air, so it is heavier and sinks while hot air is lighter and rises. This movement is known as convection, where the warmer air displaces the cooler air, causing it to rise.
Hot air is lighter than cool air, so when the balloon is filled with hot air, it becomes less dense than the surrounding cool air, causing it to rise. As the hot air inside the balloon cools, the balloon will descend. By controlling the temperature of the air inside the balloon, the pilot can control the altitude.
Hot air balloons rise because when the air inside the balloon is heated, it becomes less dense than the surrounding cooler air. This difference in density creates lift, causing the hot air balloon to float upward.
The hot air rises due to convection, which is the transfer of heat through the movement of liquids or gases. When hot and cold air meet, the hot air expands and becomes less dense, causing it to rise above the denser, cooler air.
Hot-air balloons can rise up into the air because hot air is lighter, allowing it to float up into the sky.
Hot air
Hot air balloons like those from "King Tut Balloons" rise because hot air is lighter than cool air. A burner heats the air inside the balloon, making it less dense than the cooler air outside. This causes the balloon to lift gently into the sky, offering a magical flight over stunning landscapes like Luxor’s temples and pyramids.
if you mean how the hot air in a hot air balloon makes it rise, its because hot air is less dense than cold air. when cold and hot air meet the cold air sinks thus making hot air left to rise.so when you put hot air in a balloon the air would rise. hope this helps.

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.
yes
