Hot air rises in the atmosphere because it is less dense than cold air. When air is heated, its molecules move faster and spread out, making the air less dense. This lighter, less dense hot air then rises above the denser, cooler air around it. This movement of hot air rising and cold air sinking creates convection currents in the atmosphere.
Hot air rises in the atmosphere because it is less dense than cold air, creating a buoyant force that causes it to move upward.
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.
Helium and hot air balloons rise because the air inside them is lighter than the surrounding air. Helium is lighter than the nitrogen and oxygen in the atmosphere, causing it to float upward. Similarly, hot air balloons rise because the heated air inside is less dense than the cooler air outside, creating lift.
Yes, It is because in a hot air balloon the hot air rises and the cool air falls down.
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 air balloons float because hot air displaces cool air in the atmosphere
It's a three part question...Theres not any additional imformation.It's a question I need answered.[1][How fast does hot air rise in the atmosphere]?[2]Does hotter air rise faster?[3] What is the average rate of cooling when hot and cold air mix,the average temperature drop?

Particles in the air are heated by a burner in the hot air balloon, causing them to expand and become less dense. This creates a pressure difference between the inside and outside of the balloon, allowing it to rise and float in the atmosphere.
Hot air rises due to the process of convection. As air is heated, it becomes less dense and more buoyant, leading it to rise above cooler, denser air. This movement creates circulation patterns that drive weather systems and air currents in the atmosphere.
Hot-air balloons can rise up into the air because hot air is lighter, allowing it to float up into the sky.

Similarly, hot air balloons rise because the heated air inside is less dense than the cooler air outside, creating lift.
Hot air
For the same reason that it happens in other fluids. The hot air (in this case) has a tendency to rise, and colder air, to sink, due to differences in density.
It is because a hot air is a light matter while a cold air is a heavy matter of gas. Like, the difference of low(hot) pressure and high(cold) pressure area.
Hot air balloons work by heating the air inside the balloon with a burner, making it less dense than the surrounding air. This temperature difference creates lift, allowing the balloon to rise and float in the atmosphere. The pilot can control the altitude by adjusting the temperature inside the balloon.
