Vapor Pressure Calculator

Formula: Vapor pressure: P2=P1 exp( Hv)R (1T1 1T2 ) )

Enter the unknown value as ‘ x ‘

Vapor Pressure of Interest at T2 (P2)= atm

The Corresponding temperature (T2)= kelvin

The Temperature at Another Point(T1)= kelvin

Vapor Pressure at the Known Temperature T1(P1)= atm

The Molar Enthalpy of VaporizationH)= joule/mole

x =

 

Vapour Pressure Calculator is a free online tool that displays the vapour pressure of a solid or liquid at a given temperature. BYJU’S online vapour pressure calculator tool makes the calculation faster and it displays the vapour pressure in a fraction of seconds.

How to Use the Vapour Pressure Calculator?

The procedure to use the vapour pressure calculator is as follows:

Step 1: Enter the temperature, molar enthalpy of vaporization, and x for the unknown in the input field

Step 2: Now click the button “Calculate x” to get the graph 

Step 3: Finally, the vapour pressure at the specific temperature will be displayed in the output field

What is Meant by Vapour Pressure?

The vapour pressure is defined as the pressure which is caused by the evaporation of liquids (or solids). The vapour pressure may be liquid state vapour pressure or solid-state vapour pressure.  The vapour pressure is formed due to the thermodynamic equilibrium state with the solids or liquids at a given temperature in the closed system. The three main factors of the vapour pressure are temperature, surface area and the intermolecular force. Generally, the molecules vapour pressure differs at different temperatures.
