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 is the difference between freezing and boiling point
Both start by boiling a liquid, but in distillation the vapor produced by boiling is captured, cooled, and condensed back to a liquid.
The boiling point of liquid nitrogen is -195.8°C and the boiling point of water is 100°C. Therefore, that's a difference of 295.8°C.
boiling is the heating of a liquid 'til it begins evaporating whereas burning is the heating of a solid 'til it crumbles and turns to carbon
Boiling : the temperature increases substance changes its form from liquid to gas atoms of the substance moves with the high kinetic energy by absorbing heat Condensing : the temperature decreases substance changes its form from gas to liquid atoms of the substance loses atomic kinetic energy by losing heat
the maximum amount of solvent mixier and their boiling point called evaparation
what is the difference between freezing and boiling point
difference between critical temp and boiling point
The difference between the freezing and boiling points vary from substance to substance.
Boiling Point Elevation
The boiling point of hexane is 68 degrees Celsius, while the boiling point of butanol is 117.4 degrees Celsius. There is a difference of 49.4 degree Celsius between their boiling points.
Both start by boiling a liquid, but in distillation the vapor produced by boiling is captured, cooled, and condensed back to a liquid.
Evaporation is completely natural. Boiling isn't. Hopefully this helps.
When you steam the lobster, it is placed in a basket above a pot of boiling water. When you are boiling the lobster, it is placed directly into the boiling water.
Heating almost to boiling means that the liquid doesn't boil. Heating just to boiling means the liquid boils.
The difference between them is that boiling is when you heat a liguid and it turns into a gas, vaporization is when a liquid changes into a gas and evaporation occurs at the surface of a liquid beneath its boiling point.
False because the difference between it is 180
