fixedboilingpoint

Fixedboilingpoint is a term that refers to the specific temperature at which a pure substance boils under a given atmospheric pressure. This boiling point is a physical property unique to each substance. For instance, water boils at 100 degrees Celsius at standard atmospheric pressure (1 atmosphere). If the pressure changes, the boiling point also changes. For example, at higher altitudes where atmospheric pressure is lower, water will boil at a temperature below 100 degrees Celsius. Conversely, at pressures higher than standard atmospheric pressure, the boiling point will be elevated.

The concept of a fixed boiling point is crucial in various scientific and industrial applications. It is used for identification and purification of substances through techniques like distillation. For example, if a liquid is expected to boil at a certain temperature and it boils at a different temperature, it suggests the presence of impurities. Chemists rely on tabulated fixed boiling points of known compounds to confirm their identity or to assess the purity of synthesized materials. Understanding and measuring fixed boiling points are fundamental aspects of thermodynamics and physical chemistry, providing insights into intermolecular forces and phase transitions.
