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 construction in the capillary tube does not allow the mercury to flow back into the bulb when the thermometer is taken out from the patient's mouth.

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.

The capillary tube of the thermometer ( in case of a mecury thermometer).

There is none. In the case of a thermometer, it will depend on the relative dimensions of the bulb and the capillary 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.

1.Ensure that the glass at the bulb is thing so that heat energy can be transferred between the thermometer and the substance more rapidly2.Ensure that the diameter of the capillary tube is small. In this way, a smaller expansion in the mercury causes a large linear expansion in 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

A thermometer has a capillary tube but a mercury switch in a heater thermostat has mercury that just rolls back and forth.

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

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

As the temperature rises or falls the liquid in the reservoir (bulb) of the thermometer rises or falls ) the liquid expands (heats up) or contacts (cools off). The volume change is made visible in the capillary (tube) in the part of the thermometer with the scale. This is the only part of the thermometer into which the extra volume and expand.Increasing the volume of fluid or decreasing the diameter of the capillary makes the changes more apparent/

A capillary tube is a tube with a very small diameter.

A clinical thermometer has the following main features. It has a capillary tube that contains mercury or colored alcohol. A bulb that one places onto a surface to measure the temperature of the body is the other part.

The red liquid in a thermometer is Mercury, which is usually encased in a glass tube

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.

A precision capillary tube with a graduated scale and a liquid such as mercury or alcohol that will expand as the temp increases.

Its a tube used to transmit internal refrigerant pressure from a remote sensing bulb to an expansion valve diaphragm............................

the height of a capillary tube is not dependent on

Thermometer. They contain Mercury which is a metal.

because,the adhesive force of mercury in more compared to the cohesive force which acts on a capillary tube. that's why mercury falls in capillary tube

If the last word was meant to be "alcohol", then the answer is a thermometer.

There is a constriction in the tube, forming a bottle-neck.. Shaking the thermometer will get the mercury back to the bulb at the bottom.
