srálivosti

Srálivosti is a Czech noun that appears in some technical writings as a nonstandard or variant form related to the standard term srážlivost. In standard usage, srážlivost denotes a property or tendency to collide, precipitate, or cohere, depending on the context. The word is built from the verb srážet (to collide, to precipitate) and the suffix -livost, which marks a quality or tendency.

In scientific contexts, srážlivost commonly refers to the propensity of particles or droplets to encounter each other and interact. This can describe collisional coagulation in aerosols, droplet coalescence in clouds, or aggregate growth in planetary science and materials research. The concept is closely linked to how often collisions occur (collision rate) and how likely collisions lead to sticking or reaction (sticking probability or efficiency).

Measurement and application of srážlivost typically involve rate coefficients that combine a collision cross-section, relative velocity, and a probability of interaction. Factors that influence it include particle size, charge, surface properties, humidity, temperature, and the surrounding medium. In meteorology, it affects precipitation formation; in materials science, it influences the aggregation of nanoparticles.

Orthography and usage note that srálivosti is not the standard form. The conventional Czech term is srážlivost (and its inflected forms such as srážlivosti). srálivosti may occur as a misspelling or regional variant, but most authoritative texts prefer srážlivost to avoid ambiguity.
