Answer 1

Answer:

BOILING

A process in which a substance changes its state from the liquid state to the gaseous state .

EVAPORATION

A process in which a substance changes its state from the liquid state to the gaseous state without boiling

Fast Slow.

Bubbles are formed No bubbles formed

Occurs throughout the liquid Takes place only from the exposed surface of the liquid.

EVAPORATION

Occurs at a definite temperature –

Boiling point Occurs at all temperature

Source of energy needed Energy supplied by surroundings

$\sf{\green{\large{Evaporation:- }}}$

• Evaporation is a process that takes place continuously at all temperature.
• Evaporation takes place only at the surface of the liquid.
• It always causes cooling.

$\sf{\purple{\large{Boiling:-}}}$

• Boiling takes place at a definite temperature. At this, boiling point, the vapour pressure of the liquid becomes equal to the atmospheric pressure.
• And boiling takes place from even below the surface of the liquid in the form of bubbles.
• No cooling.
