Okay, basically, hot air balloons trap air within them. Air, (according to the particle theory) is made of molecules and atoms that keep moving.
In order for a hot air balloon to rise, you turn on like some fire thing (sorry I don't know the name) which is placed directly under the opening of the 'balloon'. You know the principle hot air rises and cool air sinks. As the air inside the 'balloon' is heated, the atoms gain energy. They move faster in the enclosed space, bumping one another out. By bumping against one another, the atoms spread out, and thus the spaces between the particles become bigger. Now the hot air is less dense than the cool air.The hot air will rise (like how oil floats on water) and thus...you rise too!
Basically, its all about the temperature affecting the speed and energy of the air particles.
A hot air balloon works in a particle system by taking part in making it hover.
A gas burner is used in the hot air balloon to heat air. When heat is applied, particles tend to expand. Due to this the air surrounding the balloon is cooler than the air inside it, making it to rise.
yes
it would shrink in cold and expand in warm, if you really want to surprise your teacher say it has to do with particle theory
when you fill a balloon with air the air makes pressure. the air pressure maximizes the balloon fabric allowing the balloon to expand.
Balloon will not fill up the full bottle in this experiment as the air is restricted by the walls of the balloon. Balloon is a solid so the air will take its shape.

yes
a balloon car works by the air in the balloon.
yes
a hot air balloon works when the hot air blowing from the bottom pushes up the balloon which lifts it up into the sky where it moves in the direction where the wind blows .
A balloon car works by your air because you have to blow up a balloon and put it on the end of your boat.
the balloon works with the poplo force forcing it up
Hot air rises. That is how a hot air balloon works.
It is more like an observation or a hypothesis(depending on whether you have done the experiment or not).The law is the thermal expansion of gasses (Henry's Law).The theory is that a (lightweight) balloon filled with enough air that is hot enough will rise.
cotton
it works bye using fire
we describe air by answering it's properties
