What Causes Evaporation Lines?

Evaporation lines can be caused by several different factors but the most common ones are temperature and humidity. When the temperature is high the water molecules in the air can break down into hydrogen and oxygen. This process is called thermal decomposition and it’s what creates evaporation lines. The higher the humidity the more water vapor in the air and the more lines you’ll see.

How to Interpret Evaporation Lines?

When observing an evaporating liquid one can see a clear blue line on the surface as the liquid is lost from the container. This line is called the evaporation line and it can be used to help interpret the rate of liquid loss. The blue color is caused by the absorption of short-wavelength light by water molecules in the atmosphere.
