It does affect a nitrogen balloon.
This depends on the mass of nitrogen contained in the balloon.
Yes. Without gravity, a hot air balloon would rise infinitely. You could never return to the ground. Balloons tend to hover more or less. The force of the air pushing up on the balloon and the force of gravity pulling down on the balloon are usually very close to one another. This keeps the balloon at a steady height, unless you heat the air in the balloon, or let it cool.
The downward force of gravity, and the upward buoyant force resulting from the low density air inside the balloon.
Liquid nitrogen has a low temperature, and that obviously decreases the volume of the air inside the balloon. The balloon shrinks
It is filled with heated air. Since air is mostly nitrogen, a hot air balloon is mostly filled with nitrogen.
We measure it as a constant force pulling the plane toward the center of mass of the Earth, which usually coincides with the perpendicular to the ground. For simplicity, we call it "straight down".
The balloon rocket main aim is to test the force of gravity in the outer space. The main aim of the balloon rocket is to investigate all forces that affect the earth and the outer space.
No. Air or helium goes inside the balloon.
how does baking soda affect the hiegt of the balloon
The composition of air is roughly 78% nitrogen and the remainder except a negligable amount of hydrogen is more dense than nitrogen. Therefore a balloon filled with nitrogen will be less dense then the surrounding air and thus will rise. The balloon will probaly not rise, as there is insufficient lift to overcome the weight of the balloon fabric. Are you sure you don't mean Helium, or Hydrogen?
Because the balloon broke the law of gravity!
No, not directly ... it needs gravity to be present, but gravity alone won't do it. There's plenty of gravity on the moon, but a helium balloon won't rise there. A helium balloon floats in air, for exactly the same reason that a block of wood floats in water. Look up "Archimedes' Principle" and read about it.
