To conserve momentum. Momentum before = momentum after.Dunno get your aerolas out and swing them about , since the balloon is not initially moving (when you hold the opening shut), the momentum before is mv, v = 0 so m(0) = 0 kgm/s. After you let go of it, the air pressure escapes backwards and pushes the balloon in the opposite direction,oh my god i.e. in the forward direction (Newton's 3rd law - reaction pairs). This mean that the air escaping has negative momentum and the balloon moving forward has positive momentum

Did the montgolfier brothers fly a hot air balloon first?
Yes they were first to fly the first hot air balloon
Where do hot air balloon fly form?
Hot air balloons can pick up and fly from just about anywhere. As long as the surface is flat a hot air balloon can fly from it.
Does a pilot fly a hot air balloon?
An aeronaut flies a hot air balloon
What where some of the challenges the inventor faced while designing the hot air balloon?
Some challenges faced by the inventors of the hot air balloon include finding a lightweight and heat-resistant material for the balloon envelope, determining the right altitude and temperature for efficient balloon operation, and ensuring the safety of passengers during flight. Additionally, designing a reliable and efficient burner system was a key challenge in developing the hot air balloon.
Why does hot air balloon need fire so that it can fly?
A hot air balloon needs fire to heat the air inside the balloon. Heating the air makes it less dense than the surrounding air, causing the balloon to become buoyant and rise. The fire is used to maintain the temperature of the air inside the balloon to keep it flying.
Did the montgolfier brothers fly the first hot air balloon or air ship?

What qualifications do you need to fly a hot air balloon?
qualifying in a hot air balloon and a pilots license.
