Jun 11, 2024 · AnswerBot. ∙ 3mo ago. When cold and hot air mix, the hot air rises while the cold air sinks. This movement creates convection currents, resulting in a change in temperature and pressure within ...
May 28, 2024 · In a hot air balloon, the solid component is the balloon fabric, the liquid component is the fuel used for heating the air (typically propane), and the gas component is the hot air that provides ...
Sep 26, 2023 · Hot air balloons do not use helium; they are typically filled with hot air. Helium is non-flammable and more commonly used in other types of balloons like weather balloons or party balloons. The ...
May 25, 2024 · A hot air balloon uses heated air to generate lift, while a gas balloon uses a lighter-than-air gas, such as helium or hydrogen. Hot air balloons are propelled by wind currents, while gas balloons ...
Sep 17, 2023 · A hot air balloon flies because hot air inside the balloon is less dense than the cooler air outside. This temperature difference creates lift, allowing the balloon to rise and float in the air. ...
Jun 3, 2024 · A deflated hot air balloon is a balloon that has lost its inflated shape and volume, typically due to the release of hot air or gas that was used to fill it. It appears crumpled and flat on the ...
Aug 29, 2023 · A hot air balloon does not have any mean of steering and does not have permanent flotation. An airship has a permanent means of flotation (lighter than air gas bags) and a means of propulsion.
May 21, 2024 · Therefore, air is considered a gas rather than a liquid. Air is a liquid by far only hot air is a gas. :D. (._.) Air can be a gas or liquid if cooled enough. Air is a mixture of a number of gases ...
Jun 10, 2024 · Yes, convection is the process in which hot air rises due to its lower density compared to cooler air. This creates a circulation pattern as the hot air moves upwards and the cool air moves downwards.
May 22, 2024 · Hot air balloons are steered by changing altitude. The air currents are often going different directions at different altitudes, and by changing altitude you can get into an air current going the ...
