[A change in the state of silica in water under external weak influences]
Abstract:
The role of silica impurities, which can significantly contribute to the state of water environment and its response to external factors, has been studied. The nonequilibrium state of silica in water, its evolution with time, and its dependence on the prehistory of a water sample were shown. Reversible freezing-thawing of water induces long-term changes in the ratio of the monomeric and polymeric forms of silica, which slowly relax to the initial state. It was shown that the "field-free" magnetic vector potential has a real effect on freezing. With the use of the alternating vector potential, its maximum effect was registered at frequencies of 3.5-4 Hz. It was proposed that this results from the stochastic resonance during the polymerization of silicic acid.

Specific Heat
For example, increasing the temperature of one gram of water by 1°C requires one calorie of heat energy and can be written as 1 cal/g-°C, or 4186 J/kg/K.
States of Water
Water freezes when the intermolecular forces are greater than the kinetic energy. Unlike most other substances, water is less dense in its solid state than in its liquid state. This is because each water molecule can form...
