In a liquid, some energetic molecules break free from the surface even when the liquid is too cold for bubbles to form. What is the name of this process?

مائع میں، کچھ توانائی بخش مالیکیول سطح سے آزاد ہو جاتے ہیں یہاں تک کہ جب مائع بلبلوں کے بننے کے لیے بہت ٹھنڈا ہو۔ اس عمل کا نام کیا ہے؟
Explanation
Evaporation is the process by which molecules escape from the surface of a liquid to become vapor, even if the liquid is below its boiling point.
This occurs when some molecules have enough energy to break free from the surface tension of the liquid and turn into vapor.
Key Points:
- Boiling occurs when a liquid is heated to its boiling point, causing bubbles to form and rise to the surface.
- Condensation is the process by which vapor is converted back into a liquid.
- Convection is the transfer of heat through the movement of fluids.
