Sagot :

When the atmospheric pressure is equal to the vapor pressure of the liquid, boiling of liquid will begin.

What happens when atmospheric pressure is equal to the vapor pressure of liquid?

When the atmospheric pressure is equal to the vapor pressure of the liquid, boiling will begin. The bubbles formation started to the liquid molecules which have gained enough energy to change to the gaseous phase.

The vapor pressure of ethanol is 5.95 kPa at 20.0 °C, and its vapor pressure is 53.3 kPa at 63.5 °C.
