In a gas particles are spread out so much that they are independent. The particles move fast.
Yes. A single gas particle experiences gravitational force.
positive
It would look very small because subatomic particles are small.
A lighter gas particle can have the same kinetic energy as a heavier particle if it has a greater speed. Kinetic energy is determined by both mass and velocity, so a lighter particle can compensate for its lower mass by moving faster. The average kinetic energy of gas particles at a given temperature is the same, regardless of their individual masses.
I dknt know
Because the particles are further apart (look up the particle model) :)
Yes. A single gas particle experiences gravitational force.
They look like any normal particle, only seen when magnified but even then you can't really describe it.
all of them
A non-example of a particle would be a continuous, unbroken physical substance, such as a fluid or gas. These substances do not consist of individual, distinct particles like atoms or molecules.
A molecule, SO2
When particles receive energy (like heat) usually it causes the particle to vibrate. If this particle is next to another particle, the vibration causes the particle next to it to vibrate. This vibration is the heat energy being given off, and colliding with the next particle, which then collides with the next particle, then the next, etc.This is the case with solid and liquid particles, however gas particles use convection, which is where the gas particle hits another particle, and so transfers some of the energy (such as heat) to that particle.Conduction ConvectionA;vibrate;B;vibrate:C A->->->;collide;B->->;collide;C

A photon is a tiny particle of light that does not have a physical appearance like a solid object. It is often described as a wave or a particle, depending on how it is observed. Its appearance can be described as a massless, energy-carrying particle that travels at the speed of light.
they are far apart
they look like small circles which float around
