i think that u were asking about the difference between evaporation and boiling.

Some key points are

1) Evaporation takes internal energy while for boiling we have to provide external energy or we have to reduce the pressure.

2) As Evaporation takes internal energy therefore evaporation results in cooling while this is not observed in boiling.

3) Evaporation occurs below saturated temperature while Boiling occurs at and above saturated temperature.

4) Evaporation occurs at liquid-vapor interface while Boiling occurs at solid liquid interface.

5) Vapor bubbles are formed in Boiling while in Evaporation there are no bubble formation and no bubble motion.

6) There are different regimes of boiling (like nucleate boiling, transition boiling, film boiling etc.) while these regimes are not present in Evaporation.

7) Rate of Evaporation is much slower than the Boiling.

8) Example of Evaporation are

Water in a lake at 20°C, evaporates to air at 20°C and 60 percent relative humidity since the saturation pressure of water at 20°C is 2.34 kPa, and the vapor pressure of air at 20°C and 60 percent relative humidity is 1.4 kPa. Other examples of evaporation are the drying of clothes, fruits, and vegetables; the evaporation of sweat to cool the human body; and the rejection of waste heat in wet cooling towers.

i am hoping that the above comparison will give you the clear picture about the evaporation and boiling.

What are the difference between freezing point and boiling point?

The freezing point is the temperature at which a liquid turns into a solid, while the boiling point is the temperature at which a liquid turns into a gas. The freezing point is typically lower than the boiling point for a substance.


Why is there a difference in boiling points between h2o and h2s?

The difference in boiling points between water (H2O) and hydrogen sulfide (H2S) is primarily due to differences in molecular structure and intermolecular interactions. Water molecules form stronger hydrogen bonds compared to hydrogen sulfide molecules, leading to a higher boiling point for water. Additionally, water molecules are more polar compared to hydrogen sulfide molecules, which also contributes to the difference in boiling points.


What is the difference between the boiling points of water and liquid nitrogen?

The boiling point of water is 100 degrees Celsius, while the boiling point of liquid nitrogen is -196 degrees Celsius. This means that water boils at a much higher temperature compared to liquid nitrogen.


What differences does distillation rely on to separate out parts of a solution?

Different boiling points.


What is the difference between boiling and distillation?

Boiling is the process of changing a liquid into vapor by heating it, whereas distillation is a method of separating components of a liquid mixture based on differences in boiling points. Distillation involves boiling a liquid to create vapor, then cooling and condensing the vapor to obtain purified components.

difference between simple and fractional distillation?

The key difference between fractional and simple distillation is that fractional distillation is used when the components in the mixture have closer boiling points, while simple distillation is used when the components in the mixture have a large difference in their boiling points
