1. The thermometer in the still head measures the boiling point of the liquid in the distillate. We can be sure of this because the boiling point of the boiling flask will vary based on how many compounds are in it. The thermometer measures the temperature of the vapor at the top of the column; this vapor will be cooled through the condenser and will condensate in the graduated cylinder at the product end of the apparatus. Therefore we are measuring the boiling point of the distillate vapor that is being condensed and collected.

What is the use of thermometer adapter in laboratory?
I believe you are talking about for a reaction vessel (round bottom flask). It allows the thermometer to be very close to the reaction without being in the vessel. It can be used in cases where you cannot have oxygen getting into the system or if the products may break the thermometer or stick to it etc
Why does the doctor dip the thermometer in a liquid before use?
it is alcohol to disinfect the thermometer
What is the advantage of simple distillation to fractional distillation?
Whether it is better to use fractional or simple distillation depends on the liquids being separated and on the boiling points of the liquids. When there is a great difference between the boiling points of the liquids, simple distillation may be a better option. Likewise, if there is a small difference in boiling points, then fractional distillation is used.
Why is the entire mercury bulb of the thermometer must be below the level of the side arm in order to obtain an accurate reading of the distillation?
The boiling point of the distillate is normally the temperature of the vapour. If the bulb of the thermometer is placed too high, above the sidearm leading to the condeser, the entire bulb will not be heated up by the vapour of the distillate, and the temperature will be too low. however, if the bulb of the thermometer is placed too low, too near to the surface of the boiling water, the thermometer will show a too-high reading.Thus, the bulb of the thermometer should be placed at the sidearm or just below the sidearm in order to obtain an accurate reading of the distillation.

If i use a thermometer what will be the temperature in the plastic cup with hot water?
That depends on how hot the water is in the cup. Use the thermometer to measure it and see.
What is the use of distillation adapter?
A distillation adapter has one primary use. That primary use is in organic chemistry processes. It is meant to hold a thermometer to determine boiling point.

What is the best position of thermometer in distillation range?
Just place it on the top bozo
What is used in distillation?
The most important components of a laboratory distillation installation are: - source of heat - refrigerant (condenser) - a recipient for the liquid to be distilled - a recipient for the collected liquid after distillation - glass tubes for connections - thermometer
What are the Sources of error in distillation?
boiling chips are not added to the distillation flask. the thermometer bulb is placed in the boiling liquid. the water to the water-jacketed condenser is not turned on.
What is the function of the thermometer in the process of distillation?
To indicate when the vaporization temperature of the medium being distilled has been reached.
Why shouldn't the thermometer touch the walls of the distillation head?
because the sides of the beaker will be slightly at high temperature
Use in a sentence for thermometer?
use thermometer in fever.

What substances use distillation?
Vodka, Brandy, Whiskey and Rum are all alcoholic products that use Distillation.
How can you measure a body temperature?
What kind of thermometer you use to measure the body temperature
Where does the thermometer be used at?
Depends on the thermometer. If it's a weather thermometer, then you use it outside. If it's a body temperature thermometer, then you use it in the mouth or behind.
