If the boiling point is recorded when the liquid enters the capillary tube will it be recorded too high or too low?
If the boiling point is recorded when the liquid enters the capillary tube, it will likely be recorded too low. This is because the liquid may not have reached its true boiling point yet, as the temperature can drop briefly upon entering the narrower environment of the capillary tube. Additionally, any heat loss during this transition can further contribute to an inaccurately low boiling point measurement.
If the boiling point is recorded when bubbles are rapidly escaping the capillary tube will it be recorded too high or low and why?
If the boiling point is recorded when bubbles are rapidly escaping the capillary tube, it will likely be recorded too low. This is because the presence of bubbles indicates that the liquid is boiling, but the temperature may not have stabilized at the true boiling point, which is typically defined at the point of constant temperature just before the liquid fully transitions to vapor. Rapid bubble formation can lead to fluctuations in temperature readings, resulting in an inaccurate measurement.
Why a capillary tube is put in a fusion tube?
A capillary tube is placed in a fusion tube to allow for precise temperature measurement and control during the fusion process. The capillary tube contains a small sample that can be heated uniformly, enabling the observation of the sample's melting point. This setup helps in determining the purity and characteristics of the substance being tested. Additionally, the capillary tube provides a clear view of the sample's behavior as it transitions from solid to liquid.
Why mercury falls in capillary tube?
Mercury falls in a capillary tube due to the combination of capillary action and gravity. Capillary action is the tendency of a liquid to be drawn up into a narrow tube against the force of gravity. When the adhesive forces between the mercury and the walls of the capillary tube are greater than the cohesive forces within the mercury, the mercury will move downward in the tube.
Why do you use a new capillary tube for melting point determination each time?
It is not easy to be cleaned inside.

What causes a liquid to enter a capillary bell during a boiling point measurment?
During a boiling point measurement, a liquid enters a capillary bell due to the combined effects of capillary action and vapor pressure. As the temperature rises, the vapor pressure of the liquid increases, creating a partial vacuum in the capillary. This pressure difference, along with the adhesive forces between the liquid and the capillary walls, causes the liquid to be drawn into the narrow tube, forming a meniscus. The height of this liquid column can then be used to determine the boiling point accurately.

What is a thiele tube is used to?
A Thiele tube is a simple device used in chemistry for measuring the melting or boiling points of substances. It consists of a capillary tube attached to a thermometer and is immersed in the substance being tested. Changes in temperature are observed to determine the melting or boiling point accurately.
What is the purpose of the short length of broken capillary tube used in the determination of boiling point?
The short length of the broken capillary tube in boiling point determination serves to ensure that the liquid inside is exposed to both the heat source and the atmospheric pressure effectively. This design allows for a quicker response to temperature changes, enabling the observer to better detect the moment when the liquid begins to boil. Additionally, the short length minimizes the risk of liquid being trapped, which could lead to inaccurate readings. Overall, it aids in achieving a precise measurement of the boiling point.
What is another name for a test tube?
another name for test tube is culture tube or sample tube
