How does particles react when they change from a solid to a liquid and to a gas?
The particles become more energetic, speed up, and spread out more.
What is bigger gas particles or smoke particles?
smoke particles are bigger than gas particles.
Do lighter gas particles diffuse less rapidly than heavier gas particles?
No, heavier gas particles diffuse slower than lighter gas particles
Does gas have fast moving 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.
What kind of path do the particles of a gas follow?
Particles of a gas are in a disorderly motion (Brownian).
How does particles react when they change from a solid to a liquid and to a gas?
The particles become more energetic, speed up, and spread out more.
What is a postulate of the kinetic-molecular theory?
all particles are always moving
How does gas explode?
Gasses in the atmosphere are given some energy (activation energy), this energy is used for the activation of the explosion. As a few gas particles react, they then have higher energy and as they collide into other air particles it causes them to react. This happens rapidly and thus an explosion occurs. I think. Think of it as an exothermic reaction, but uncontroled.
What is bigger gas particles or smoke particles?
smoke particles are bigger than gas particles.
Do lighter gas particles diffuse less rapidly than heavier gas particles?
No, heavier gas particles diffuse slower than lighter gas particles
What must particles do to react?
Collide
Why are the hot gas particles moving faster than cool gas particles?
Because hot gas particles have greater kinetic energy than cold gas particles
Does gas have fast moving 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.
Why can the particles of gas change and the particles of solids not?
Particles of a solid are attached to each other, by chemical bonds. Particles of a gas are not.
What particles move independently of each other?
Gas particles move very fast because the particles are separated and have enough space to move around.
How do positive and negative particles react?
They attract
How the motions of gas particles are related to the pressure by the gas?
is motions of gas particles are related to the pressure exerted by the gas
