КАПИЛЛЯРНЫЕ ЯВЛЕНИЕ-CAPILLARY PHENOMENA 
CAPILLARY PHENOMENA - a set of phenomena caused by the action of 
interfacial surface tension at the interface of immiscible media; To K. I am. 
Usually refer phenomena in liquids caused by the curvature of their surface, 
bordering other liquids, gas or own. ferry. KI is a particular case of surface 
phenomena. In the absence of gravity, the surface of the liquid is always curved. 
Under the influence of surface tension, the limited volume of liquid tends to 
take the form of a sphere, i.e., to occupy the volume with min. Surface. Gravity 
significantly changes the picture. A liquid with a relatively low viscosity rapidly 
takes the form of a vessel into which it is filled, and its free surface (not 
adjacent to the walls of the vessel) in the case of sufficiently large liquid masses 
and a large area of the free surface is practically flat. However, as the mass of 
the liquid decreases, the role of surface tension becomes more significant than 
the force of gravity

СМАЧИВАНИЕ – WETTING 
Wetting — is the contact between a liquid and a solid surface, resulting from 
intermolecular interactions when the two are brought together.

ЛАБОРАТОРНЫЕ ЭКСПЕРИМЕНТЫ–LABORATORY 
EXPERIMENTS 
Laboratory experiments - a test under controlled conditions that is made to 
demonstrate a known truth, examine the validity of a hypothesis, or determine 
the efficacy of something previously untried using different tools or equipments.

ПЕДАГОГИЧЕСКИЙ ЭКСПЕРИМЕНТ–PEDAGOGICAL 
EXPERIMENT 
Pedagogical experiment is a special organization of pedagogical activity of 
teachers and students with the purpose of checking and justifying pre-developed 
theoretical assumptions, or hypotheses.
