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
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.
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
For a balloon that is sealed and not full the volume of air inside the balloon will increase as it is heated. This is not however how hot air balloons work. A hot air balloon is essentially a fixed volume when it is inflated. If the air inside the balloon is heated the air inside becomes less dense so some of the air exits the balloon via the mouth of the balloon. As the air inside the balloon cools it becomes more dense so some air is ingested via the mouth of the balloon to keep it full. With each heating and cooling cycle, the pressure inside the balloon remains constant, the volume of the balloon remains constant but there is this movement of air out of and back into the balloon.

the vents work because of the heat which can make the hot air balloon go up

hot air
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.
They do work.
A hot air balloon would not work on the moon.
the balloon works with the poplo force forcing it up
By using a heat burner, hte balloon pilot makes the air in the balloon lighter than normal air. Then the balloon moves upward and moves with the wind.
