I. Introduction to the phenomenon of boiling

Boiling is a liquid heated to a certain temperature, due to the thermal movement of molecules inside the liquid is enhanced, the molecular energy on the surface of the liquid reaches the saturation vapor pressure, the liquid quickly produce bubbles and bubble, the formation of boiling phenomenon. This phenomenon is common in the process of boiling water, cooking, etc., and is also an important object of study in the field of physics and engineering.

Two, the principle of boiling

The principle of boiling is the liquid is heated so that the liquid molecular activity within the liquid intensified, the heat through the conduction to the liquid under the layer, so that its temperature rises. When the temperature of the liquid rises to saturation vapor pressure, the molecular energy on the surface of the liquid reaches a critical value for evaporation, resulting in the formation of bubbles and bubbling. As the heat continues to input, the temperature of the liquid is maintained above the saturation vapor pressure, bubbles are formed one after another and bubbling, the liquid remains boiling.

Three, boiling and pressure

Boiling phenomenon and pressure are closely related. Normally, the boiling point of a liquid is the temperature at which the liquid begins to boil at atmospheric pressure. However, when the ambient pressure changes, the boiling point of the liquid will change accordingly. In high altitude or low-pressure environments, the boiling point of a liquid will decrease; while in high-pressure environments, the boiling point of a liquid will increase.

Four, research and application

Boiling is not only a common phenomenon in daily life, but also an important object of study in the field of physics and engineering. Scientists have discovered some interesting phenomena and laws through the study of the boiling process, and applied them to practical production and engineering design.

4.1 Liquid Heat Transfer

Boiling is an efficient way of heat transfer in liquids. In the boiling process, the heat movement of the molecules inside the liquid is rapidly conducted to the lower layer of the liquid, and the heat is transferred to the surface of the liquid through the formation and bubbling of bubbles, thus realizing a wide range of heat transfer. Therefore, boiling can be widely used in heat exchange equipment, boilers and other fields to improve the efficiency of heat exchange.

4.2 Cooking and Food Processing

Boiling is a commonly used process in cooking and food processing. When boiling water and cooking food, the liquid is boiled by heating, which can quickly sterilize and soften the food, etc. Boiling also intensifies the flavors in the food and improves the texture and taste of the food.

4.3 Automotive Engineering

Boiling phenomenon in the cooling system of automobile engines is also an important research topic. In the process of engine work, the coolant in the water tank is heated and boils, forming bubbles and bubbling out, thus taking away a large amount of heat generated by the engine. Reasonable design of the cooling system to ensure adequate cooling effect, for the normal operation of the engine is critical.

4.4 Other applications

Boiling phenomenon also has a wide range of applications in chemical engineering, energy utilization and other fields. For example, in the chemical reaction process, by controlling the boiling can regulate the reaction rate and temperature distribution; in the nuclear power plant, the boiling phenomenon is used to improve the efficiency of heat exchange, to achieve efficient energy conversion.
