Assuming you could even light a match in outer space, not much.
Jupiter isn't flammable. The only thing that could set it ablaze is if much much more mass were added to it so that it's gravitational field became strong enough to cause nuclear fusion at it's core, igniting it into a second sun.
The planet Saturn has an atmosphere that contains chemicals such as methane that on Earth would be highly flammable, but on Saturn they are not flammable because there is no free oxygen in the atmosphere with which to burn anything. Nothing burns on Saturn.
it appears that tossing a lit match on the face of saturn could set the atmosphere on fire but this is only my theory it would require testing to be sure
The match would go out, due to the combination of very strong winds and freezing cold temperature there.
the match would go out as there is not enough oxygen to keep it burning.
scientifically speaking,I calculate that it would become heavier.
They would both float if you had no gravity.
The feather would reach the earth first dumb@$$
Earth would be destroy due to the gravity force of that planet.
they would hit the surface at the same time, same as on earth.
nothing. the flour is all together. if it would be flour dust, the oxygen could get to the individual particles and then it could catch fire
nothing would happen because comets hit Jupiter when it is hot and it does not burn up it. if Jupiter was a a bit bigger it would start to glow.
If you dropped a hamster on its back it would go into shock.
they would die because of the gas
The Ice Would Be Crushed
Jupiter has no definite surface. If you did not have a suitable aircraft you would simply fall into the planet's interior to be crushed by the immense pressure.
Jupiter is so big that the Earth would orbit Jupiter.
scientifically speaking,I calculate that it would become heavier.
They would both float if you had no gravity.
the world would fall apart and we would all live on jupiter
Jupiter would suddenly have aquired enough mass that the temperature and pressure in its core would begin the fusion of hydrogen atoms. Simultaneously Jupiter would also have enough gravity to keep that energy from suddenly exploding outwards. That would make Jupiter a star.
The roast I just put in the oven would be ruined in about an hour.
