The closeness of particles of gas and their low speeds allow intermolecular forces to become important at certain pressures and temperatures. Which best describes this statement?


A) This is a limitation of the kinetic-molecular theory.
B) This is a postulate of the kinetic-molecular theory.
C) This describes ideal gas behavior using the kinetic-molecular theory.
D) This describes ideal gas behavior without the kinetic-molecular theory.

Sagot :

It is a limitation of the kinetic-molecular theory because closeness and low speed don't allow  intermolecular forces to become important at certain pressure and temperature.

The kinetic gas theory explains micro-particles (atoms and molecules). The kinetic theory is basically  based upon the assumption of microscopic particles . We can use it as a microscopical model.

And the kinetic theory of gases explains how gases behave by assuming that they are made up of quickly moving atoms or molecules.

Basically kinetic model is based on the below assumptions.-

I t is assumed that the gas is made by a large number of identical molecules. And molecules are moving in random directions. And also separated by the large distances as compared to their size.

The molecules collide completely elastically  without no energy loss.

Always kinetic energy is transferred between molecules through heat.
