Ångtemperaturen

Ångtemperaturen, also known as the boiling point, is the temperature at which a liquid changes into a gas or vapor at a given pressure. This temperature is a characteristic property of a substance and is influenced by the intermolecular forces between the molecules of the liquid. For water, for example, the boiling point is 100 degrees Celsius at standard atmospheric pressure. The boiling point increases with increasing pressure and decreases with decreasing pressure.

The concept of boiling point is fundamental in various fields, including chemistry, physics, and engineering. It is used to identify substances, to design and operate industrial processes, and to understand phase transitions. The boiling point can also be affected by the presence of impurities in the liquid, a phenomenon known as boiling point elevation.

In practical applications, the boiling point is used in various processes, such as distillation, where a liquid is heated to its boiling point and then condensed to separate it from other components. It is also crucial in the design of heating systems and the operation of steam engines.

The boiling point is closely related to the melting point, which is the temperature at which a solid changes into a liquid. Both are important in understanding the behavior of matter under different conditions and are essential in the study of thermodynamics and phase transitions.
