Question

does a puddle of water on the ground boil before it dries up?

Answer 1

The theory involved is Dalton's law of partialpressure and vapor pressure of matter.Our atmosphere is not a vacuum. It consists of various material, usually the elements and compounds in their gaseous state (there are also solids as dust, etc as pollutants); e.g nitrogen, oxygen, CO₂, water H₂O in the gaseous state. At any temperature there is a pressure (due only to the water vapor) below which water may exists in the gaseous state (this data is found in the so called vapor pressure data for water). Say you have a vessel which is vacuum and the room temperature is 20⁰ C. If you introduce enough water into the vessel, it will evaporateas gaseous vapor until the pressure is about 0.2 atmosphere pressure maximum. This is evaporation. Water in a plate left in the open will evaporate (same as boiling) at say 20⁰ C room temperature as long as the air is not already saturated with water vapor. Water will "boil" (evaporate) at 20⁰ C as long as thecontribution of the water vapor to the total pressure of the atmosphere (about 1 atm) is small, say < 0.2 atm.Water boils at 100⁰ C at 1 atm pressure is correct (water boils at 20⁰ C at about 0.2 atmpressure). This boiling we do in the kitchen kettle is the bubble that forms at the bottom and rises to the surface and breaks. If the temperature is below 100⁰ C, any attempt to form gas bubble would fail as the water pressure is too strong and collapses it. At 100⁰C, the water vapor pressure itself (due solely to gaseous water) reaches also 1 atm and a bubble formed can withstand the pressure of the water trying to collapse it - thus bubbling of "boiling" starts.

Question :-

Does a puddle of water on the ground boil before it dries up?

Answer :-

➡Never does a puddle of water " boil ".

➡Actually the puddle of water evaporates and hence it dries up.

These are few differences between evaporation and boiling :

➡Evaporation takes place at any temperature but boiling takes place only at the boiling point of the liquid.

➡Evaporation depends upon the surface area of the liquid but boiling does not .

➡Evaporation also occurs at the surface of the liquid while boiling takes place throughout !

Hope its helpful !
