What is a thermometer bore?

A bore refers to the extremely fine or narrow tube found in a thermometer. It is called a narrow bore or a capillary.


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.


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.

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.


Describe the structure of a thermometer?

The thermometer consists of a very fine glass tube having a very small bore and is called capillary tube. At one end of capillary tube a very thin glass bulb is provided. The bulb is filled with mercury( most of the times) or alcohol The other end of capillary tube is sealed. The capillary tube is protected by a thick glass tube called stem. On the stem are made markings. These markings are called graduations or degrees.


Why is a capillary tube thought of as a dry-type?

The Capillary tube metering device is used primarily on small fractional-horsepower refrigeration systems that have relatively constant evaporator heat loads. These systems are hermetically sealed, leak free systems with dry-type evaporators that use a minimum of refrigerant. The capillary tube metering device is a fixed bore device, itcontrols refrigerant flow by pressure drop.


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.


What has greatest capillary action?

Water has the greatest capillary action due to its strong hydrogen bonding and cohesive properties, allowing it to easily move through narrow spaces and against gravity. Other liquids with high capillary action include mercury and ethanol.
