In chemistry... it's a thin open-ended glass tube for collecting small amounts of liquid. Inserting one end of the tube into liquid allows the liquid to flow upqwards. When the liquid reaches a suitable height, a finger placed over the open end (towards the top) holds the liquid in the tube - for transferring from one place to another.

What are the essential steps for placing a solid sample in a capillary tube?
The essential steps for placing a solid sample in a capillary tube are: 1. Crush the solid sample into a fine powder. 2. Use a spatula to carefully transfer the powder into the capillary tube. 3. Use a tamper or glass rod to compact the sample down the length of the tube for accurate measurements.
How would you use capillary in a sentence?
The liquid was pulled into the small tube by capillary action.
Why do liquid rise of fall in a capillary tube?
It is because of the surface tension between liquid molecules and the inner surface of the tube. The meniscus height is determined by the inner diameter of the tube. The smaller the diameter, the higher the meniscus will climb due to capillary action.
Is mercury in any devices always in a capillary tube?
No, mercury is not always contained in a capillary tube. It can be found in devices like thermometers, barometers, and some electrical switches where it is used due to its unique properties, such as being a liquid at room temperature. Mercury can also be found in other forms in devices, such as sealed containers or as a component in some medical instruments.
What is the bore of a cappillary tube?
The bore of a capillary tube is the inner diameter of the tube, which is very small typically ranging from below 1 millimeter down to a few micrometers. It is designed to facilitate the movement of liquids through the tube using capillary action.
The height of a liquid in a capillary tube is not dependent on?
the height of a capillary tube is not dependent on
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 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?
deduce an expression for height of a liquid in capillary tube. also write practical applications of capillary action.
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 is a narrow tube that is used as a metering device?
capillary tube
The narrow tube that is used as a metering device is a?
capillary tube.
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.
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.
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.
Why does liquid rise in a capillary tube?
Liquid rises in a capillary tube due to capillary action, which is the result of adhesive and cohesive forces between the liquid and the tube. Adhesive forces between the liquid and the tube's surface cause the liquid to be attracted to the tube, while cohesive forces within the liquid molecules help pull the liquid up the tube against gravity.
