The capillary tube is the hollow opening inside the thermometer that the liquid rises or lowers in so that you can read the temperature. The bulb is the bottom portion that holds the liquid and the part you use for contact to get a temperature reading.

The capillary tube and bulb in a thermometer are typically positioned at the bottom of the thermometer. The bulb is the rounded end that collects the temperature, while the capillary tube contains a liquid that expands and contracts based on the temperature changes, leading to the reading on the thermometer scale.

Excess superheat in a capillary tube system means that there is?
Excess superheat in a capillary tube system means that there is insufficient refrigerant flow through the system. This can lead to poor cooling performance and decreased efficiency. It is important to ensure the correct amount of refrigerant is flowing through the system to prevent excess superheat.
What is a very small artery that delivers blood to the capillaries?
Arterioles are the very small arteries that deliver blood to the capillaries. They are responsible for regulating blood flow and distribution to different tissues and organs in the body.
What is responsible for capillary action of water?
Capillary action of water is due to a combination of adhesive forces between water molecules and the walls of the capillary tube and cohesive forces between water molecules themselves. This allows water to move against gravity through narrow spaces such as tubes or small spaces in soil.
Very small tube that carrys blood?
Capillary: these tiny blood vessels facilitate the exchange of nutrients, oxygen, and waste products between the blood and tissues. Their small size allows for efficient nutrient and gas exchange due to their proximity to body cells.
What is brisk capillary refill?
Capillary refill refers to how quickly the color returns to the external capillary bed following pressure that has been applied to an area. A brisk capillary refill means that the color returned to the capillary bed rather quickly.
How does a fluid expansion thermometer work?
A fluid expansion thermometer consists of a bulb filled with a liquid, typically mercury or alcohol, connected to a capillary tube. As the temperature increases, the liquid in the bulb expands and rises up the capillary tube. The temperature is read by measuring the height of the liquid in the tube, which corresponds to the temperature scale on the thermometer.
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.
What is a capillary tube in instrumentation terms?
a thermometer--
How do you increase sensitivity of mercury in glass thermometer?
Sensitivity of a thermometer is the length of increase of the liquid per degree rise in temperature. More sensitive means more noticeable expansion. So if you want to increase the sensitivity, you could have a thinner capillary tube, a larger thermometer bulb etc. :)sailesh
What does the volume of a thermometer refer to?
The volume of a thermometer typically refers to the amount of liquid (such as mercury or alcohol) contained within the thermometer's bulb and capillary tube. This liquid expands or contracts with changes in temperature, allowing the thermometer to display the temperature reading.
What is the formula between length of mercury level and temperature in degree celsius?
There is none. In the case of a thermometer, it will depend on the relative dimensions of the bulb and the capillary tube.
What is the definition of Glass thermometer?
thermometer consisting of mercury contained in a bulb at the bottom of a graduated sealed glass capillary tube marked in degrees Celsius or Fahrenheit; mercury expands with a rise in temperature causing a thin thread of mercury to rise in the tube
What is thermometer made up of?
A thermometer is typically made up of a glass tube filled with a liquid such as mercury or alcohol. The liquid expands and rises in the tube as the temperature increases, allowing the user to read the temperature from the scale on the side of the thermometer.
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.
What two items are in a thermometer?
A precision capillary tube with a graduated scale and a liquid such as mercury or alcohol that will expand as the temp increases.
How does gas thermometer functioning?
Gas thermometers operate by measuring changes in gas volume as temperature varies. When the temperature rises, the gas inside the thermometer expands, increasing the pressure and moving the liquid in a glass tube. This movement is then converted into a temperature reading based on the calibrated scale of the thermometer.
Why is the walls of long tube above the thermometer bulb are made thick?
The walls of the long tube above the thermometer bulb are made thick to provide insulation and minimize heat transfer from the environment, ensuring that the temperature measurement at the bulb is accurate and not influenced by external temperature changes. Thicker walls also help protect the thermometer from physical damage.
