What Is Thermology?

Thermology is a branch of physics that studies the properties and laws of matter when it is in a hot state. It originated from human exploration of cold and hot phenomena. Humans live in the natural world where the seasons change and the climate changes. The hot and cold phenomenon is one of the earliest natural phenomena they observe and understand.

Thermal

(Physics)

Thermal (Thermology) is a branch of physics that studies the relevant properties and laws of matter when it is in a hot state. It originated from human exploration of hot and cold phenomena.

An archeological study of the Palaeolithic site in Xihoudu, Xicheng, Shanxi, China, shows that humans began to use fire about 1.8 million years ago; abnormal temperature records have been recorded in China around 2000 BC; both East and West appeared before BC Early doctrine in the field of thermal sciences. In the Warring States Period of China, Zou Yan founded the Five Elements Doctrine. He called water, fire, wood, gold, and soil the Five Elements, which he believed was the foundation of everything. During the period of ancient Greece, Heraclitus proposed that fire, water, earth and air were the four independent elements of nature. These are the early understandings of nature.

Human understanding of thermal phenomena originates first from knowledge of fire

Thermodynamics mainly studies the thermal properties of matter from the point of view of energy conversion, and it reveals the macro laws followed when energy is transformed from one form to another.

There are various forms of material movement in nature, in addition to the existence of phenomena such as the operation of cars and trains, the rotation of lathe flywheels, and celestial movements.

In addition, there are other types of phenomena such as thermal expansion and contraction of materials, thermal conduction, diffusion, the change of conductor resistivity with temperature, and the change of solid, liquid, and vapor states of materials. The former is characterized by changes in the spatial position of objects, known as mechanical motion phenomena, and its laws are studied mechanically; a careful analysis of the latter type of phenomena will reveal that there is a common characteristic, that is, they are all related to temperature. We refer to the phenomenon that the physical properties of such materials change with temperature as thermal phenomena.

The occurrence of thermal phenomena is caused by the random movement of a large number of molecules inside the material. When discussing and studying the laws of thermal phenomena, the overall macro-mechanical motion of objects no longer belongs to the scope of discussion, and people focus on a large number of molecular motions inside the material. Different from the physical concept of mechanical motion, the motion form of macroscopic matter composed of a large number of irregularly moving molecules with thermal phenomena as the main symbol is called thermal motion.

Thermal phenomenon is the macro manifestation of thermal motion, and thermal motion is the micro essence of thermal phenomenon.

Thermal exercise is not isolated, and can often be transformed into other sports forms under certain conditions. Such as frictional heat generation, volatilization and cooling, gas heat absorption in the cylinder to perform external work, current heating through resistance, and temperature difference batteries. Therefore, studying the law of the transformation of thermal motion with other motion forms is another important basic content of thermal research.

Thermal is the study of the thermal phenomena of matter, the laws of thermal motion, and

A discipline that transforms thermal motion with other forms of motion.
