Question

Differences between evaporation and boiling

Answer 1

PLEASE MARK ME AS BRAINLIST

Answer:

What is Evaporation?

Evaporation occurs on the surface of the liquid whereas boiling occurs at the entire length of liquid

What is Boiling?

Boiling means rapid vaporization of any liquid. It happens when a liquid is heated to its boiling point. The boiling occurs in three different stages such as nucleate boiling, transition boiling and film boiling. There are no stages for evaporation.

EVAPORATION VS. BOILING

Boiling occurs when the temperature of the liquid is greater than the boiling point of the substance. Evaporation can occur at any temperature. It occurs as long as the substance remains liquid at a particular temperature.

According to Greg Bradburn, evaporation occurs when there is an increased energy present and occurs rapidly. It occurs from the bottom of the container when allowed to boil. The bubbles form at the bottom of the container and then rise on top of the container. In boiling, bubbles do not form at the bottom and rise to the surface. Evaporation occurs at room temperature and therefore, occurs at a slower rate when compared to boiling.

Answer 2

$Question$ :-

1. Difference between evaporation and boiling?

$Answer$ :-

• The process of evaporation is usually a slow and carried out process when compared to boiling .

The process of boiling is usually much quicker and the process happens quite rapidly as well.

• Evaporation usually occurs on the surface of the liquid being heated up .

Boiling usually occurs on the entire mass of the liquid that gets heated up .

• Bubbles effect is not visible in evaporation

Bubbling effect is visible during the process of boiling
