A postulate is a statement recognized as a truth. The kinetic molecular theory has five postulates. Which of the following is NOT a postulate regarding the behavior of ideal gases in terms of kinetic molecular theory? Ideal gas particles are small compared to the space between them.

Particles must not be able to move in any fixed or open container.

Their collisions must be elastic and versatile.

There are no significant interactions among the particles of a gas.

2nd option is NOT a postulate of kinetic theory of gases

Explanation:

actually particles move in straight random motion and create bombardment with the molecules and container

nanotechnology is a powerful tool in biomaterials research as it creates numerous possibilities for the engineering of functional molecules. nano-bio refers to projected ability to incorporate biomimicry into various materials at nanoscale.  

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence,   the electronegativity (or the ability to attract electrons) is lessened."
