Learn how to use the boiling point calculator with a step-by-step procedure. Get the boiling point calculator available online for free only at BYJU'S.
The boiling point of a compound can be determined from additive constitutive properties, but the melting point can be estimated only with the aid of nonadditive constitutive parameters. The melting point of some non-hydrogen-bonding, rigid compounds can be estimated by the equation MP = 0.772 * ...
By definition, the Boiling Point is the temperature at which the vapour pressure of the liquid equals the surrounding pressure, and the liquid turns into vapour. The phenomenon of boiling is pressure dependent and hence, the Boiling Point of a liquid may change depending upon the surrounding pres...
How do I calculate the boiling point? To calculate the boiling point of a given substance: Use the Clausius–Clapeyron equation: ln(P₁/P₂) = -ΔH/R × (1/T₁ − 1/T₂) Insert the pressure values at state 1 and state 2, P₁ and P₂. Substitute the value of tempera...

In addition, if the heat of vaporization and the vapor pressure of a liquid at a certain temperature are known, the boiling point can be calculated by using the Clausius-Clapeyron equation: TB=1/T0−RlnP/P0/ΔHvap−1 TB is the boiling point at the pressure of interest, R is the ...
Boiling Point Elevation Formula The equation for boiling point elevation is $$\Delta T_{b}=K_{b}m $$ where {eq}\Delta T_{b} {/eq} is the change in boiling point, {eq}K_{b} {/eq} is the molal boiling point elevation constant, and {eq}m {/eq} is the molality of the solu...

Boiling Point Elevation Equation The formula used to calculate boiling point elevation is a combination of theClausius-Clapeyron equationand Raoult's law. It is assumed the solute is non-volatile. ΔTb=Kb·bB where ΔTb is the boiling point elevation ...
boiling point is in degrees Fahrenheit (°F); pressure is expressed in inches of mercury (inHg); and altitude should be put into the equation in the imperial unit — feet (ft). However, when using this boiling point at altitude calculator, you can use a wide range of units for each va...
