Clausius-Clapeyron Equation
Describes the relationship between vapor pressure and temperature, showing that vapor pressure increases with temperature. Vapor Pressure
The pressure exerted by a vapor in equilibrium with its liquid or solid phase at a given temperature. Enthalpy of Vaporization
The heat required to convert a liquid into a gas at constant temperature and pressure. Gas Constant
A physical constant denoted as R, with a value of 8.314 J/mol·K, used in various equations of state. Natural Logarithm
The logarithm to the base e, where e is an irrational constant approximately equal to 2.71828. Inverse Temperature
The reciprocal of temperature, often used in thermodynamic equations, represented as 1/T. Slope
In the context of the Clausius-Clapeyron equation, it represents -ΔHvap/R in a plot of ln P versus 1/T. Normal Boiling Point
The temperature at which a liquid's vapor pressure equals 760 torr, allowing it to boil under normal atmospheric pressure. Torr
A unit of pressure equivalent to 1/760 of an atmosphere, commonly used in measuring vapor pressure. Kelvin
The SI base unit of temperature, where 0 K is absolute zero, used in scientific temperature measurements. Linear Form
A representation of the Clausius-Clapeyron equation as a straight line, useful for plotting ln P against 1/T. Two-Point Form
A form of the Clausius-Clapeyron equation used when comparing two sets of temperatures and pressures. Equilibrium
A state where the rate of vaporization equals the rate of condensation, resulting in a constant vapor pressure. Condensation
The process by which a gas transforms into a liquid, often occurring when vapor pressure decreases. Vaporization
The process of converting a liquid into a gas, typically requiring heat input to overcome intermolecular forces.
