Kiehumispisteeltään

Kiehumispisteeltään refers to the boiling point of a substance. The boiling point is the temperature at which a liquid turns into a gas at a given pressure. It is a physical property that is characteristic of each pure substance. For example, the boiling point of water at standard atmospheric pressure (1 atmosphere) is 100 degrees Celsius (212 degrees Fahrenheit).

The boiling point is determined by the strength of the intermolecular forces within the liquid. Substances with strong intermolecular forces, such as hydrogen bonding, will have higher boiling points than substances with weaker forces, like van der Waals forces. Pressure also plays a significant role. At higher pressures, more energy is required to overcome the intermolecular forces, thus increasing the boiling point. Conversely, at lower pressures, the boiling point decreases. This is why water boils at a lower temperature at high altitudes where atmospheric pressure is less.

Understanding the boiling point is crucial in various scientific and industrial applications. It is used for identifying pure substances, separating mixtures through distillation, and designing chemical processes that involve phase changes. For instance, in the petrochemical industry, fractional distillation separates crude oil into different components based on their varying boiling points. The term "kiehumispisteeltään" specifically refers to the state or characteristic of a substance concerning its boiling point.
