What are the characteristics of the liquid used in a liquid in a glass thermometer?
The liquid in a glass thermometer is typically a non-toxic and non-reactive liquid such as mercury or colored alcohol. These liquids have a high coefficient of thermal expansion, allowing them to accurately measure temperature changes by expanding or contracting within the narrow capillary tube of the thermometer.
Why is a laboratory thermometer not used to measure the body temperature?
A thermometer used to measure body temperature is extremely accurate over an extremely small range of temperatures. It will give the temperature to the tenth of a degree. A laboratory thermometer does not have the partial degree separations but gives the temperature over a much wider range of temperatures.
The narrow tube that is used as a metering device is a?
capillary tube.
What we called the tendency of liquid molecules to rise spontaneously up tubes with narrow diameters?
That is capillary attraction.
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 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 are the constrictions in a thermometer?
The constriction in a thermometer is a narrow region in the capillary tube where the liquid (like mercury or alcohol) is forced to flow through. This helps to amplify the rise or fall in temperature, making it easier to read.
Why is capillary tube narrow in thermometer?
The capillary tube in a thermometer is narrow to allow for precise measurements of temperature changes. A narrow diameter increases the sensitivity of the liquid inside the tube, enabling it to expand or contract more noticeably with small temperature fluctuations. This design ensures that even slight changes in temperature result in a clear, measurable movement of the liquid column, enhancing the accuracy of the readings. Additionally, the narrow tube helps minimize the effect of external factors, such as air currents, on the liquid's movement.

What is the prefix for Capillary?
The prefix for "capillary" is "capill-" which means small or narrow, often referring to small blood vessels in the body.
What we called the tendency of liquid molecules to rise spontaneously up tubes with narrow diameters?
That is capillary attraction.
What is a capillary features?
A capillary has a very narrow lumn and very thin wall. These features maximize diffusion of nutrients, wastes, and oxygen.

Why is the thread of a thermometer narrow?
The narrow thread of a thermometer allows it to respond more quickly to changes in temperature. This design ensures that the thermometer provides a more accurate reading by allowing the liquid inside to expand or contract faster in response to temperature changes.
