Enter the liquid volume and the temperature into the calculator to determine the vapor volume. This calculator assumes ideal gas behavior to estimate the volume of vapor produced from a liquid at a given temperature.
Vapor Volume Formula
The following formula is used to calculate the vapor volume.
VV = LV * (T + 273.15) / 293.15
Variables:
- VV is the vapor volume (liters)
- LV is the liquid volume (liters)
- T is the temperature (°C)
To calculate the vapor volume, multiply the liquid volume by the ratio of the temperature in Kelvin to the standard temperature (20°C in Kelvin). Note that this calculation assumes that the pressure is constant at 1 atm and that the gas behaves ideally.
What is Vapor Volume?
Vapor volume is the amount of space that the vapor phase of a substance occupies at a given temperature and pressure. It is an important parameter in various industrial and scientific applications, such as chemical engineering, thermodynamics, and material science. The vapor volume can be estimated using the ideal gas law for gases that behave ideally, or more complex models for real gases.
How to Calculate Vapor Volume?
The following steps outline how to calculate the Vapor Volume.
- First, determine the liquid volume (LV) in liters.
- Next, determine the temperature (T) in degrees Celsius.
- Convert the temperature from Celsius to Kelvin by adding 273.15 to the Celsius temperature.
- Use the formula VV = LV * (T + 273.15) / 293.15 to calculate the vapor volume (VV) in liters.
- After inserting the variables and calculating the result, check your answer with the calculator above.
Example Problem :
Use the following variables as an example problem to test your knowledge.
liquid volume (LV) = 2 liters
temperature (T) = 100°C
