Indole is an organic compound with the formula C 6 H 4 CCNH 3. Indole is classified as an aromatic heterocycle . It has a bicyclic structure, consisting of a six-membered benzene ring fused to a five-membered pyrrole ring.
The bulk modulus of water ice ranges from 11.3 GPa at 0 K up to 8.6 GPa at 273 K. [44] The large change in the compressibility of ice as a function of temperature is the result of its relatively large thermal expansion coefficient compared to other common solids.
The partition coefficient between n-Octanol and water is known as the n-octanol-water partition coefficient, or K ow. [62] It is also frequently referred to by the symbol P, especially in the English literature. It is also known as n-octanol-water partition ratio. [63] [64] [65]

The role of water in the association equilibrium is ignored as in all but the most concentrated solutions the activity of water is constant. K is defined here as an association constant, the reciprocal of an acid dissociation constant. Each activity term { } can be expressed as the product of a concentration [ ] and an activity coefficient γ ...
Self-diffusion describes the diffusive motions of molecules within themselves e.g. the movement of a water molecule in water. According to the IUPAC definition, [1] the self-diffusion coefficient of medium is the diffusion coefficient of a chemical species in said medium when the concentration of this species is extrapolated to zero concentration.
