Porézní

Porézní is a Czech adjective meaning porous. It describes a material that contains many small holes or pores. These pores can be interconnected or isolated. The degree of porosity can vary significantly between different materials.

Materials can be naturally porous, such as sponges, pumice, or certain types of soil and rock. They can also be manufactured to be porous, for example, in the production of filters, ceramics, or insulation materials. The presence of pores influences a material's properties, including its density, strength, absorbency, and thermal conductivity.

In physics and engineering, porosity is an important characteristic. For instance, in soil science, porosity affects water infiltration and retention. In materials science, it can be manipulated to create lightweight yet strong structures, or to facilitate the passage of fluids or gases. The study of porous materials, known as pore science or the science of porous media, is a multidisciplinary field.
