A hot air balloon rally is a rally with the well known hot air balloon. People might even get married and do other fun activities there. It's kind of like a festival.
Smoking in a hot air balloon
A hot air balloon can descend by either releasing hot air from the balloon envelope or by opening a vent at the top of the balloon to allow some of the hot air to escape. This reduces the buoyant force that is keeping the balloon in the air, causing it to descend slowly. The pilot can control the descent rate by carefully managing the release of hot air.
A hot air balloon flies because it is filled with hot air. Hot air rises and causes the balloon to lift from the ground.
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. By controlling the temperature of the air inside the balloon, the pilot can control the balloon's ascent and descent.
A hot air balloon is called such because it is filled with hot air to make it rise. When the air inside the balloon is heated, it becomes less dense than the surrounding cooler air, causing the balloon to float upwards.
Hot-air balloons function on the principle that warm air rises, and the balloon mechanism holds onto hot air to ascend. Despite this, the hot air can't stay in the balloon forever, the opening at the top of the balloon allowing a slow and steady flow of the hot air out of the balloon and a gentle descent to the ground.
A hot air balloon pilot is called an aeronaut.
The hot air inside the balloon expands, making the hot air balloon fly.
D: The hot air inside the balloon becomes less dense than the air outside the balloon.
A hot air balloon is called an hot air balloon because, the inside is heated up to make it less dense, allowing it to rise. Meaning, your heating up the air inside the balloon, hence, the name: Hot air balloon.
The answer is fairly simple, while some believe that a balloon bursts when near hot air because the balloon simple melts, it actually has to do with the pressure inside the balloon. When near hot air, the air inside the balloon expands slightly, causing a change in pressure, and causing the balloon to burst.
When a hot air balloon is filled with the hot air the air around the balloon is a lot denser. So by convection the balloon rises and the less dense air is replaced by dense air underneath it.
