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.
The rise of water in a narrow test tube is called?
The rise around the edges is called the meniscus, like capillary action this is caused by the adhesion of the liquid molecules to the walls of the container. In a large bore tube like a test tube or graduated cylinder this pulls up the edge and creates a concave meniscus, in a smaller bore tube this actually pulls the liquid toward the top of the tube.
When water is placed in a thin glass tube it tends to climb up the walls of the tube This effect is known as capillary action What causes this capillary action?
Hydrogen Bonding
What happen when capillary tube of sufficent length is dipped in liquid?
When a capillary tube of sufficient length is dipped into a liquid, the liquid rises or falls within the tube due to capillary action, which is the result of adhesive forces between the liquid and the tube's walls, and cohesive forces within the liquid itself. The height to which the liquid rises or falls is determined by the tube's diameter, the liquid's properties (such as surface tension and viscosity), and the interaction between the liquid and the tube material. This phenomenon is commonly observed with water in narrow tubes and is essential in various biological and engineering applications.
How is polarity related to capillary attraction?
Because of the polarity of water, it exhibits a greater cohesion and adhesion to itself and other substances. This means that water holds on to itself more firmly than it does other substances.

Why is capillary tube fixed in Ostwalds viscometer?
The capillary tube is fixed in the Ostwalds viscometer is for passing the liquid.
What is the function of capillary tube?
The capillary tube is used on the inside of the refrigerators. It is a long copper tubing that is used as a thruster.
Derive an expression for expression for rise of liquid in a capillary tube?

How can you measure the diameter of capillary tube by using vernier caliper in traveling microscope?
To measure the diameter of a capillary tube using a traveling microscope and vernier caliper, place the capillary tube on a flat surface. View the capillary tube through the traveling microscope to measure the external diameter. Then, use the vernier caliper to measure the internal diameter by gently inserting the capillary tube between the jaws of the caliper to get an accurate measurement. Subsequently, calculate the average diameter using the two measurements.

What may be the trouble if a capillary tube unit frosts down the suction tube?
If a capillary tube unit frosts down the suction tube, it may indicate a restriction in the capillary tube, improper refrigerant charge, or a problem with the system's airflow. It is recommended to check for any blockages in the capillary tube, ensure the system has the correct refrigerant charge, and inspect the airflow to troubleshoot and resolve the issue.
