Hot air balloons were primarily used in World War 1 for reconnaissance and observation purposes. They provided military forces with a vantage point to gather intelligence on enemy movements and positions, significantly enhancing situational awareness on the battlefield. Although eventually replaced by airplanes for aerial reconnaissance, hot air balloons played a crucial role in the early stages of the war by aiding artillery targeting and coordination. Their use exemplified the evolving nature of warfare and the importance of aerial technology during the conflict.

Aeroplanes fought in the air in world war one. It was also called an 'aerial dogfight' .

Professor Thaddeus Lower sent messages about locations in a hot air balloon. Balloons were used by the Union army from 1861 to 1863 in the Civil war.
Kapua, are you asking this
If there is warm air in the balloon, cooler air makes the balloon rise and if there is cold air in the balloon warmer air makes the balloon fall.
Yes
its effect increases as balloon moves upward
depends on mass and if you include the air. same mass and not including the air they both weigh the same, air just expands the balloon and lowers the effect of gravity.
Turning on the burner in a hot air balloon heats the air inside the balloon, reducing its density. This decrease in density causes the balloon to become lighter than the surrounding air, which helps it to rise. The heated air adds buoyancy, allowing the balloon to ascend.
A hot air balloon rises due to the principle of buoyancy. As the air inside the balloon is heated, it becomes less dense than the surrounding air, causing the balloon to float upwards. This effect is similar to how a helium balloon rises in the atmosphere.

A balloon floats in the air when the molecules inside the balloon are less dense. The gas inside a helium balloon is in essence "lighter" than the air around it, causing a buoyancy effect which makes the balloon float. This can also be seen in hot air balloons when the air molecules are heated by the propane torch and excited, thus creating a less dense environment inside of the balloon compared to outside of the balloon.
Pulling the cord on a hot air balloon opens a valve that releases hot air from the balloon, causing it to sink. By releasing hot air, the balloon becomes less buoyant and starts descending. This allows the pilot to control the balloon's altitude and descend to the desired landing spot.
Because it was the first war where aircraft had a decisive, strategic effect on the course of the war.
When a balloon is pricked by a pin, the air inside the balloon will quickly escape, causing the balloon to deflate rapidly. The balloon will shrink in size and eventually become flat.
