Boiling occurs spontaneously at all temperatures.
Boiling occurs spontaneously at all temperatures.
The correct option is B False
Again, go down to the basics.
Definition of Boiling:
Boiling is a special case of evaporation. It is the rapid conversion of a liquid into vapour by means of formation of bubbles. During boiling, vaporization is not restricted to the surface only but takes place throughout the bulk of the liquid.
The condition of free vaporization throughout the liquid is called boiling.
The temperature at which the vapour pressure of a liquid is equal to the external pressure is called the boiling temperature at that pressure.
So, what did we learn from definition?
→ It occurs only at a specific temperature at which the vapour pressure equals the imposed pressure on the liquid surface.
Note: Evaporation occurs spontaneously at all temperatures but not boiling.
