WHAT IS THERMODYNAMICS

Thermodynamics is the branch of physics that has to do with heat and temperature and their relation to energy and work. The behavior of these quantities is governed by the four laws of thermodynamics, irrespective of the composition or specific properties of the material or system in question. The laws of thermodynamics are explained in terms of microscopic constituents by statistical mechanics. Thermodynamics applies to a wide variety of topics in science and engineering, especially physical chemistry, chemical engineering and mechanical engineering.

WET STEAM

Wet steam is characterized by the vapor quality, which ranges from zero to unity. When the vapor quality is equal to 0, it is referred to as the saturated liquid state (single-phase).On the other hand, when the vapor quality is equal to 1, it is referred to as the saturated vapor state or dry steam (single-phase)Between these two states, we talk about vapor-liquid mixture or wet steam (two-phase mixture).
