Evaporation causes cools....it makes things cool and if you put a wet paper on a dry thermometer watch,Watch the temperature of the thermometer will drop extremely fast!! Try it at homee or school , anywhere, you'll love it<3 but make sure that the temperature of your house or school is warm and try not to open any windows or doors during the experiment!
Good Luck! :) Hope you like my Answer!<3 (well watever i got a level 4 when i told my teacher this information)*

What are Disadvantages of alcohol in glass thermometers?
... as compared to what? - I believe the temperature range is somewhat limited, compared to some other substances.
Is there a difference between residue on ignition vs. residue on evaporation?
Yes. The residue left is material that did not ignite or products of the ignition reaction.The residue remaining after evaporation is the non-volatile substances in the solutionsubjected to the evaporation.
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.
How will the density change if the temperature increased to 125?
The density of most substances will change if temperature is increased. The amount of change depends on the difference between the two temperatures.
What substances can be separated by evaporation?
For example a solid from a liquid; evaporation of water from sea waters give salt.

What do thermometers actually detect about the moving particles that make up a sample of matter?
Thermometers detect the average kinetic energy of the particles in a sample of matter. As the temperature increases, the particles move faster and have higher kinetic energy. This increase in kinetic energy is then measured by the thermometer, allowing us to determine the temperature of the sample.

What two substances are used in the thermometer's glass tube?
MERCURY is commonly used in thermometers designed for medical and elevated temperatures, and ALCOHOL (with a coloured dye) is used in medical and very low temperature thermometers. Both these use glass tubes. Very high temperature thermometers contain Gallium, which is a liquid at room temperature, in a quartz tube.
How miscible liquids can be sepearated?
Separation by destillation (evaporation / condensation) or freezing out (crystallisation at lower temperature). Both are not absolutely effective, no pure substances are obtained.
What abnormal substance will decrease due to evaporation?
The mass of all substances decrease by evaporation.
What is a difference in flow rates and viscosities between substances when heated?
Viscosity and flow rate increases with the temperature.
Why is it that when air is blown over hot substances is cools?
Evaporation
Why does some substances freeze faster then others?
They may have lower freezing point, or there may be bigger temperature difference between them and the environment.
What methods is used to separate mixtures of soluble substances such as dies?
Evaporation of the water?
Evaporation occurs when two fronts of widely different moisture levels meet?
Evaporation occurs at different temperatures for different substances. Evaporation is just the change of state of matter from liquid to gaseous.
