Kuumutustemperatuur

Kuumutustemperatuur, also known as the boiling point, is the temperature at which a liquid turns into a gas or vapor. This transition occurs when the vapor pressure of the liquid equals the external pressure. The boiling point is a characteristic property of a substance and varies with the applied pressure. For example, water boils at 100 degrees Celsius at standard atmospheric pressure, but at higher altitudes where the pressure is lower, water boils at a lower temperature.

The boiling point of a liquid is influenced by several factors, including the nature of the liquid, the presence of impurities, and the external pressure. Pure substances have a specific boiling point, but the addition of impurities can raise the boiling point, a phenomenon known as boiling point elevation. Conversely, the boiling point can be lowered by the application of reduced pressure, as seen in the process of vacuum distillation.

The boiling point is an important concept in various fields, including chemistry, physics, and engineering. It is used to identify substances, design industrial processes, and understand phase transitions. For instance, in chemical engineering, the boiling point is crucial for the design of distillation columns used in the separation of mixtures.

In summary, kuumutustemperatuur, or boiling point, is a fundamental property that describes the temperature at which a liquid transitions to a gas under specific conditions. It is influenced by the nature of the liquid, impurities, and external pressure, and plays a significant role in various scientific and industrial applications.
