TB-220804-V-4.4 Pumps of Various Types Teaching and Laboratory Equipment
I.Introduction of thermal dynamics
Thermodynamics is a discipline that studies the properties and laws of thermal motion of matter from a macroscopic perspective. It belongs to the branch of physics, and it and statistical physics constitute the macroscopic and microscopic aspects of thermal theory respectively.
Thermodynamics mainly studies the thermal properties of matter from the point of view of energy transformation. It suggests the macroscopic laws that energy follows when transforming from one form to another, and summarizes the thermal theory obtained from the macroscopic phenomena of matter. Thermodynamics does not investigate the microscopic structure of matter composed of a large number of microscopic particles, but only cares about the thermal phenomena exhibited by the system as a whole and the basic laws that must be followed for its change and development. It is satisfied to describe and determine the state of the system with a few macroscopic state quantities that can be directly felt and observed, such as temperature, pressure, volume, concentration, etc. Through a large number of observations and experiments on thermal phenomena in practice, it is found that there is a relationship between the macroscopic state quantities, and their changes are mutually restrained. In addition to the properties of matter, the constraint relationship must also follow some basic thermal laws that are applicable to any matter, such as the zeroth law of thermodynamics, the first law of thermodynamics, the second law of thermodynamics, and the third law of thermodynamics. Thermodynamics is the basis and starting point of the above-mentioned basic laws obtained from experimental observations, applying mathematical methods, and through logical deduction, to obtain the relationship between various macroscopic properties of matter and the direction and limit of macroscopic physical processes, so it belongs to phenomenology. theory, and the conclusions drawn from it have a high degree of reliability and generality.
