How is a glass thermometer read accurately?
To read a glass thermometer accurately, hold it at eye level and look at the level of the liquid inside the tube. The temperature is where the liquid stops rising. Make sure the thermometer is clean and not tilted for an accurate reading.
Who element used of the glass tube of clinical thermometer to measure thermometer?
mercury
Explain how an ordinary glass fever thermometer is designed?
An ordinary glass fever thermometer is typically made of a sealed glass tube filled with mercury or dyed alcohol. It has a calibrated scale along the length of the tube to measure temperature. When the thermometer is placed in contact with a warm object, the temperature causes the liquid inside to expand and rise up the scale, indicating the temperature value.
What is liquid-in-glass thermometer?
A liquid-in-glass thermometer is a type of thermometer that consists of a glass tube filled with a liquid, typically mercury or alcohol, which expands or contracts with changes in temperature. The level of the liquid in the tube corresponds to the temperature, allowing for temperature measurement.
How do you read a glass thermometer?
Hold the thermometer at the top and look at the liquid level inside the tube for the temperature. Make sure the thermometer is at eye level and take note of the number closest to the liquid level to get the temperature reading.
The function of a Mercury thermometer?
A Mercury thermometer measures temperature by relying on the expansion and contraction of the liquid mercury inside the glass tube. As the temperature changes, the mercury expands or contracts, causing it to rise or fall in the tube, indicating the temperature.
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.
Is the external bulb of a thermometer also made of mercury?
No, the external bulb of a thermometer is typically made of glass to hold the mercury inside. Mercury is usually contained within the glass bulb to measure temperature accurately without exposing the user to the toxic substance.
What makes a liquid-in-glass thermometer sensitive to a small change of temperature?
A liquid-in-glass thermometer is sensitive to small temperature changes because the liquid inside expands and contracts with changes in temperature. This expansion and contraction leads to a noticeable movement of the liquid in the narrow capillary tube, making it easier to detect even small temperature changes. Additionally, the glass tube and thinness of the liquid column increase the sensitivity of the thermometer.
Which element is used in the glass tube of clinical thermometer to measure tepperature?
MERCURY
Which element is used in the glass tube of a clinical thermometer to measure temperature?
mercury
What is the purpose of using a bulb thermometer?
A bulb thermometer is used to measure temperature by relying on the expansion and contraction of a liquid (typically mercury or colored alcohol) inside a glass tube. When the temperature changes, the liquid expands or contracts, moving up or down the tube and indicating the temperature on a scale.
