Final answer:
The relation Πm=κV is an empirical expression based on experimental observations, which fits within the framework provided by the Kinetic Molecular Theory (KMT). The KMT connects empirical gas laws to the microscopic behavior of molecules, which has been supported by experiments. The correct option is C.
Step-by-step explanation:
The relation Πm=κV that you are referring to is likely an empirical expression based on experimental observations, which is option C.
This type of relation is part of the empirical foundation of gas law behavior. Empirical laws such as Boyle's, Charles's, Amontons's, Avogadro's, and Dalton's laws are derived from exhaustive experimental data and observations rather than purely theoretical models.
The Kinetic Molecular Theory (KMT) is a theoretical framework that provides a microscopic explanation for these empirical laws, connecting them with molecular behavior. KMT is based on postulates about molecular motion that have been supported by experimental evidence as they explain the gas laws effectively.
However, this theoretical model does not exclude the confirmation of its principles through experimentation. In physics and chemistry, an iterative process of theoretical hypothesis and experimental verification is commonly employed.
New empirical data can refine or validate theoretical models such as KMT, and in turn, these models can predict behaviors that can be experimentally verified. Option C. is the correct one.
