Well, as far as I know, all particles are made of molecules which in turn are made of atoms which again in turn are made of protons, electrons and neutrons. Going further, the protons and neutrons are made of quarks, electrons are a fundamental particle and therefore not made of anything.
However, there are some gases, the noble gases (helium, neon, argon, krypton, xenon, radon) that are found naturally as single atoms. Therefore, particles of a gases might be "molecules" or "atoms," depending on the gas.
No it is not true
Gas particles are in a permanent and chaotic motion.
true
Yes, it is true.
Yes, is true.
The solid particles are closer.
flase
Yes, it is true.
it is probably a gas
FalseThe particles of a solid are packed closely together and don'thave as much movement as the particles of a gas or liquid.True
Yes, it is true.
If the container is rigid, then its volume cannot change. However, if more gas particles are pushing on the walls, then it is the pressure that is changing.
