Hi all,
I have a question on vapor pressure. As far as I understood, a liquid will flashes into gas when the absolute pressure it is experiencing (in a pipe / in the atmosphere) is lower than the liquid's vapor pressure (assuming temperature is constant).
Everyone knows that gasoline forms a vapor cloud when it is released into the atmosphere. But a lots of sources I came across on the internet states that the vapor pressure of gasoline ranges between 20kPa - 80 kPa at room temperature on average, so if that is true, how does gasoline form a vapor in the atmosphere?
Thank you~
