Water - or other liquids - will evaporate at practically any temperature. Boiling is defined as the temperature at which the partial vapor pressure is equal to the atmospheric pressure. In practical terms, it means that the boiling water (or other liquid) can't get any hotter assuming the pressure doesn't change. You'll also see lots of bubbles rising from the boiling liquid (but before it is boiling, there will also be a few bubbles).

What occurs at the boiling point of water?
Evaporation .
Boiling and evaporation are both forms of what?
Boiling and evaporation are both forms of changing liquids into gas. Boiling occurs when the liquid reaches its boiling point, while evaporation can occur at any temperature.
How is evaporation different from boiling?
as the evaporation occurs under the atmospheric pressure that is492degr and the boiling point occurs above the atmospheric pressure different liquids have different boiling points just the boiling point of water is 100deg c
How are evaportion and boiling different?
Evaporation occurs at the surface of a liquid at any temperature as long as the substance is a liquid. Boiling occurs throughout the liquid and occurs at the boiling point.
What does evaporation and boiling have in common?
Evaporation is a type of vaporization of a liquid that occurs only on the surface of a liquid. The other type of vaporization is boiling, which, instead, occurs on the entire mass of the liquid.
When vaporization takes place on the surface of a liquid is called?
If vaporization takes place at the surface of a liquid, it is called evaporation. but when evaporation occurs throughout the substance it is called boiling.
What process occurs as matter changes state from liquid to a gas?
Boiling, the term for that is boiling point.
What is the name of the process that changes a substance from a liquid to a gas at a temperature below the substances boiling point?
This is called evaporation. It is different from boiling because it only occurs at the top layer of molecules of the liquid, while the latter occurs in the whole body of the liquid.
What is the three differences between evaporation and boiling?
Boiling occurs when the vapour pressure becomes equal to the external pressure while evaporation is the escape of molecules from the surface. Bubbles appear in boiling while not in evaporation. Temperature does not effect the rate of boiling while evaporation is fast at high temperature and slow at low temperature.
What is the different between vaporization evaporation and boiling?
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.
What is the difference of 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.
