ABSTRACT

The two biggest phenomena of water collide in a problematic of modern urbanism-these are water cycles and water types (ocean/sea water, land water, atmosphere water and water in living organisms).

2 HEAT BALANCE

Water is known in three states. Solid, liquid and gaseous. During the change from one state to another, heat is released or consumed. During the change from solid to liquid or gaseous state, it gains high mobility thanks to which it is capable of quick motion. Water also has the highest specific heat capacity, thus the ability to receive thermal energy from known materials. With its ability to bind and release energy, and transfer skills, reflection and dissipation of energy, water in all its states according to the needs cools or heats the planet. It is keeping it at a temperature that supports life on Earth (Kravčík, 2007, Poórová et al. 2014).
