In the most general sense, all gases have the subatomic particles of protons, neutrons and electrons. What arrangements they happen to be in depend on what gas you happen to be observing at the time. For example, Hydrogen is a gas at room temperature, but does not have any neutrons. On the other extreme, something like carbon needs to be heated to much higher temperature to become a gas (assuming it doesn't get to burn and turn into carbon dioxide). Another logical level of consideration is: what is the gas made of? Is it a monatomic or diatomic gas (like oxygen or nitrogen), or is it a compound (like water or the much larger molecules of plastics, which can be extremely long)? In these cases, molecules or atoms would be the particles.
Particles in a gas are free to move at random in any direction.
number of moles of gas particles
The particles of a solid are attracted strongly to other particles around them locking them into a fixed position in which they may only vibrate but not move freely from one position to another. The particles of a gas are the opposite. Not strongly attracted, but move randomly about bouncing off of other gas particles. This allows the gas particles to move to any position, not just remain surrounded by the same few particles.
No,they don't because when the particles in gas ovecome the force of attraction they move more freely making the particles have more energy. Solid particles are tightly packed with a strong force of attraction making them have the least amount of energy compared to the other states(liquid and gas).
gas pressure is the result of simultaneous collisions of billions of gas particles with an object
This is not an ideal gas and gas laws are are only approximately applicable.
smoke particles are bigger than gas particles.
No, heavier gas particles diffuse slower than lighter gas particles
Because hot gas particles have greater kinetic energy than cold gas particles
yes. gas has the fastest moving particles and a solid has the slowest moving particles and particles in a liquid are moving faster than solid particles but not as fast as gas particles.
Particles of a solid are attached to each other, by chemical bonds. Particles of a gas are not.
Gas particles move very fast because the particles are separated and have enough space to move around.
is motions of gas particles are related to the pressure exerted by the gas
No. Gas particles move much faster than solid particles.
Gas is the form, there is no form of gas, the particles in gas move freely, they actually vibrate.
number of moles of gas particles
Unless the particles collide
becausse the particles in gas are far apart.
