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.
How is vaporization and boiling different?
boiling is when you heat up water to 100oc or 212of then if you keep it long enough it will turn into water vapour since particles first vibrate a little away from each other then they get too hot then they fly there is a difference its just a matter of time for it to happen :J
List 2 similarities and 2 differences between the processes of boiling and evaporation?
Similarities: Both boiling and evaporation involve the phase change of a liquid to a gas. Both processes require the input of energy in the form of heat. Differences: Boiling occurs at a specific temperature (boiling point) for a given pressure, while evaporation can occur at any temperature. Boiling happens throughout the liquid, while evaporation occurs only at the surface of the liquid.
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.
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?
The process is called evaporation. It occurs when a substance changes from a liquid to a gas at a temperature below its boiling point, usually at the surface of the liquid.

Boiling and evaporation are both forms of what?
Both boiling and evaporation are forms of vaporization. Vaporization is the process in which a liquid turns into a gas. Boiling is when vaporization occurs throughout the entire liquid, while evaporation is when vaporization occurs only at the surface of the liquid.

A pure substance boils only at a certain temperature?
Each liquid boils at a different temperature, but the temperature it boils at is called the Boiling Point. For example, the boiling point of water is 212 Fahrenheit.This specific temprature is dependant on the pressureon the liquid at that time, as an example at ahigher temperatures the boiling point is higher.
At what temperature can vaporization occur?
Vapourisation (as opposed to Boiling which occurs at "BOILING POINT" only) occurs at all temperature. The rate of vapourisation depends on the type of material (substance) you are talking about. Generally the lighter the substance (i.e the less dense it is) the faster it vapourises. Hence alcohol (which is less dense than water) vapourises faster than water. Water vapourises at all temperature (even at 0C) but boils at 100C.
Difference between evaporation and boiling?
The difference in evaporation and boiling is simple. Just imagine a beaker and being placed on the hot plate. The liquid it beginning to evaporate and the their is a gradient in the water because not all of the water is reaching 100 degrees Celsius at once. Some of it is beginning to evaporate (change in the state from a liquid to a gas) the other is beginning to boil! Remember boiling is a characteristic property and once it is reached the temperature doesn't continue to increase. Hope this helped!Vaporization if the phase change from a liquid to a gas. Evaporation and boiling are both mechanisms for vaporization to occur. Evaporation occurs at the surface of the liquid. It is the primary method by which water moves from bodies of water into the atmosphere. It is a much slower process than boiling. Boiling occurs when a liquid is heated to the boiling point. During boiling, water evaporates throughout the entire liquid very fast, rather than just at the surface.Evaporation happens only at the surface of a liquid and occurs at any temperature (so long as the substance is a liquid at that temperature). However, as most people are aware, liquids evaporates faster at a higher temperature. Boiling, on the other hand, happens throughout the bulk of a liquid, usually starting from some site on the inside of the container and rising in a bubble to the surface. It only happens when the temperature is above the boiling point of that substance.
Why is evaporation a surface phenomenon whereas boiling is a bulk phenomenon?
Boiling occurs in bulk and at the boiling point; all of the liquid is hot enough that any additional energy will cause it to become a gas. Evaporation occurs at the surface and at a temperature under the boiling point, because only at the surface can the hotter components of the atomic or (usually) molecular components of the liquid escape from the liquid, when most of the liquid is not hot enough to change into the gas phase.
What change of state occurs when you boil a kettle of water?
The only changes of state in pure boiling water is from liquid to gas.
Compare and contrast between boiling and evaporation?
Evaporation takes place at any temperature but boiling takes place only at a substance's boiling point.
