it entirely depend on what kind of a system you are working with. g is the probablity (number of accessible states) and k ln g is entropy and probablity is directly related to g
Entropy
The thermodynamic entropy S, often simply called the entropy in the context of thermodynamics, is a measure of the amount of energy in a physical system that cannot be used to do work. It is also a measure of the disorder present in a system. The SI unit of entropy is JK-1 (Joule per Kelvin), which is the same unit as heat capacity
Yes, changed in entropy refer to changed in mechanical motion. Entropy is a measure of the number of specific ways in which a thermodynamic system may be arranged, commonly understood as a measure of disorder.
The second law of thermodynamics, generally stated, is that the entropy of an isolated system always increases in any natural process where change occurs. In a system at equilibrium, of course, the entropy remains constant.
It is related to the 2nd law of thermodynamics
entropy persists
The entropy of the universe is increasing
entropy of thermodynamic systems
In thermal equilibrium, and only in thermal equilibrium, entropy is constant.

relationship between the thermodynamic quantity entropy
An isoentropic process is a chemical or thermodynamic process in which entropy does not change. An example a reversible adiabatic process is isoentropic.
I don't think entropy can get less than zero
