Why do you separate a salt solution using boiling instead of evaporation?
Boiling a salt solution will have the same effect as natural evaporation, but will be much faster. The water will boil off and leave the salt behind.
Why water evaporate faster in a china dish as compared to test tube?
Evaporation is a process that occurs only at the surface of a liquid. If the same volume of liquid is put in a dish rather than a test tube then the liquid will have a bigger surface area allowing more room for evaporation.
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.
Do molecules move faster in room temperature water?
room temperature water. the hotter water get the more quickly it moves
Does clean water evaporate faster then dirty water?
yes it does. The evaporation rate of water is dependent on the number of molecules that can be presented to the evaporating surface. Anything in the water besides water will decrease this density and slow the process of evaporation.
Does higher boiling point evaporate faster?
Evaporation and boiling are the same process, liquid water is converted to water vapour. To convert from liquid to gas the water molecules have to absorb heat. The rapidly the heat is supplied, the faster the liquid water changes to a gas. In evaporation this heat comes from the air the water is exposed to, the surface the water sits on and the heat already in the water (hot water cools as it evaporates). This process is relatively slow compared to boiling water where a lot of heat is being put into the system by the stove or hot plate. It takes the same amount of heat to boil or evaporate the same amount of water. Boiling provides this heat much more quickly. Therefore boiling water evaporates much more quickly.

Why does boiling water evaporate faster than regular water?
A high temperature favors evaporation.
What is the main difference between boiling and evaporation?
The main difference between boiling and evaporation is that boiling is much faster. Boiling also often takes place at the bottom of the fluid (where the heat source usually is) whereas evaporation takes place only at the surface. So boiling can produce bubbles, while evaporation doesn't.Evaporation is the process by which molecules in a liquid state (e.g. water) spontaneously become gaseous (e.g. water vapor), without being heated to boiling point. It is the opposite of condensation. Generally, evaporation can be seen by the gradual disappearance of a liquid, when exposed to a significant volume of gas.Boiling is very rapid evaporation starting within a container of water.Normally evaporation occurs at a much slower rate than boiling because most evaporation occurs with room temperature water.Boiling occurs only when the liquid is heated to the boiling point, and vapor bubbles come from the bulk of the liquid. In evaporation, vaporization occurs only at the surface of the liquid, not throughout the liquid, and this occurs at lower temperatures.
Process of water turning into vapour?
Water most often becomes vapor when it is heated up. As water is heated up, its molecules vibrate faster. When water reaches its boiling point, the molecules are unable to remain a liquid and transition into a gas.

Can you evaporate sea water without boiling?
Yes. Evaporation happens just about all the time, it's just faster at boiling point.
Why is water best in radiators?
This is because water has a high boiling point, which means, it boils faster as compared to other liquids/fluids and therefore radiator faster.
How is particle motion related to evaporation?
KE of particles in a liquid will differ, the faster ones can escape as vapour even at temperatures lower than boiling.

Where does evaporation happen in every day life?
Liquid water evaporates constantly, and that is the most usual type of evaporation that we encounter since water is the most common liquid. Things get wet, then they dry off, through a process of evaporation. You might dry a wet object with a towel, but then the towel is wet and also dries through evaporation. And even if you are making things dry faster by putting clothing into a dryer, or by using a hair dryer on your hair, this is still a process of drying by means of evaporation. The evaporation is faster if you heat things up.
