laboratory thermometer is used to measure the boiling point of a liquid because it has greater range.
Which is used to determine boiling point of liquids?
The Capillary Method to Determine Boiling Point
As the liquid is heated, the vapor pressure of the sample increases and gaseous vapor starts to enter the glass capillary tube. This forces out the air trapped inside and results in bubbles emerging from the bottom of the capillary tube.
Which instrument is used to measure boiling point?
The instrument used to measure boiling point is Thermometer.
Which instrument should be used to measure the boiling point of a liquid and why a clinical thermometer It is easier to read B clinical thermometer it has a greater range C laboratory thermometer it is easier to read D laboratory thermometer it has a greater range?
Answer: (d) Laboratory thermometer; it has a greater range.
What increases boiling point?
Large molecules have more electrons and nuclei that create van der Waals attractive forces, so their compounds usually have higher boiling points than similar compounds made up of smaller molecules.
Which instrument is used to determine melting point and boiling point?
A melting-point apparatus is a scientific instrument used to determine the melting point of a substance. Some types of melting-point apparatuses include the Thiele tube, Fisher-Johns apparatus, Gallenkamp (Electronic) melting-point apparatus and automatic melting-point apparatus.
Why water is used in boiling point determination?
The reason of this is, that the steam condenses to pure water on the bulb and stem of the thermometer, and as this water has a large surface, any further heat communicated will cause part of the water to evaporate without a rise of temperature occurring.
What liquid has the highest boiling point?
Explanation: Acetone 56.0 ∘C .
