A pilot usually has 2-4 passengers.

When you inflate a balloon, the air goes inside the balloon and fills it up. The air molecules push against the walls of the balloon, causing it to expand and take on its inflated shape.
A hot air balloon lifts a basket of people by heating the air inside the balloon with a burner. As the air inside the balloon becomes warmer, it becomes less dense than the cooler air outside. This temperature difference causes the balloon to rise, carrying the basket and passengers with it.
A hot air balloon needs a flame to heat the air inside the balloon, making it less dense than the surrounding air. This temperature difference creates lift, allowing the balloon to float upwards. Without the flame, the air inside the balloon would cool down and the balloon would descend.
To launch a hot air balloon, the pilot first inflates the balloon with a large fan to fill it with cold air. Then, a burner is used to heat the air inside the balloon until it becomes hot and the balloon starts to rise. Once it is fully inflated and upright, the passengers can board and the balloon will take off.

The first hot air balloon to take people up was in 1783 in Paris, France.

It's a gas. The air molecules are free to move around anywhere in the balloon.
Parents are free to take children of any age on a hot air balloon.

The air inside cools. Cool air shrinks. The balloon gets smaller.

When air is blown into a balloon, the air molecules take up space inside the balloon and increase the pressure of the air, causing the balloon to expand. The increase in pressure inside the balloon pushes against its elastic walls, causing it to stretch and take up more space.
The number of air particles in a balloon can vary depending on the size of the balloon and the pressure of the air inside. On average, there are approximately 2.5 x 10^22 air molecules in a standard-sized balloon.
