what is the difference between evaporation and boiling?
Boiling occurs when the vapour pressure of a liquid is equal to the atmospheric pressure surrounding it. This occurs at a specific temperature called the boiling point (e.g. 100C is the boiling point for water).
Evaporation is similar to boiling in that it results in a liquid turning into a gas. The difference, however, is that evaporation occurs at temperatures below the boiling point. Some molecules will spontaneously obtain enough energy to move into the gaseous state.
Evaporation is slower than boiling, but its rate increases as the temperature moves closer to the boiling point.

So water is continuously being evaporated into gaseous phase, correct.
what is the difference between the partial pressure and vapor pressure?
However, if the atm pressure is greater than the vapor pressure and the vapor pressure inturn is greater than the partial pressure, evaporation takes place.

lolwut
I am confused , what is the vapor pressure while we talk about a liquid
