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.

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.
The blood vessel that only allows one corpuscle to go through at a time is called a capillary.
Capillary action is a process powered by adhesion that causes water molecules to move upward through a narrow tube such as the stem of a plant. The adhesive force allows them to attach to the vessel walls.
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.
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.
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.
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.
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
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.
There is none. In the case of a thermometer, it will depend on the relative dimensions of the bulb and the capillary tube.
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
In this answer I m referring to the normal thermometers. Not the electronic thermometers. There is a very very thin capillary tube incide the thermometer which is filled with mercury and it has a bulb aT one end. When it touches a surface, the mercury expands, rises in the capillary and the temperature is shown.
A bore refers to the extremely fine or narrow tube found in a thermometer. It is called a narrow bore or a capillary.
A precision capillary tube with a graduated scale and a liquid such as mercury or alcohol that will expand as the temp increases.
A gas thermometer measures temperature by the variation in volume or pressure of a gas.One common apparatus is a constant volume thermometer. It consists of a bulb connected by a capillary tube to a manometer. The bulb is filled with a gas such that the volume of the gas in the bulb remains constant. The volume is related to temperature by k, known as Charles's Law . The pressure of the gas in the bulb can be obtained by measuring the level difference in the two arms of the manometer. Gas thermometers are often used to calibrate other thermometers.
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.
