A glass stem thermometer measures temperature through the expansion and contraction of a liquid, typically Mercury or colored alcohol, contained in a sealed glass tube. As the temperature increases, the liquid expands and rises in the narrow stem, while it contracts and descends as the temperature decreases. The temperature is read by observing the level of the liquid against a calibrated scale printed on the glass. This method allows for accurate temperature readings based on the physical properties of the liquid used.
What else can I help you with?
Which device has a liquid in glass components?
thermometer
Function of thermometer?
The function of a thermometer is to measure temperature.
How do you increase accuracy in a liquid in glass thermometer?
There are several ways:use a liquid whose coefficient of thermal expansion is near constant,use a liquid with low vapour pressure,use a bulb with a relatively larger bulb and thinner stem,calibrate the thermometer carefully.
What can you measure Fahrenheit with?
a thermometer
What is a Low-temperature thermometer?
what is the name of a thermometer which can measure low temperatures
How does a glass stem thermometer measure temperature?
A glass stem thermometer measures temperature by using the principle of thermal expansion. The liquid inside the glass stem expands or contracts with temperature changes, causing the level of the liquid to move up or down the scale. This movement indicates the temperature.
Why is the stem of a thermometer designed as a magnifying glass?
The stem of a thermometer is not designed as a magnifying glass. The stem of a thermometer is typically narrow to allow for more accurate temperature readings, as it reduces the amount of time it takes for the reading to stabilize. The magnifying glass may be used for easier reading of the temperature scale on the thermometer.
Why does the glass stem in a clinical thermometer act as a magnifying glass?
The glass stem in a clinical thermometer acts as a magnifying glass because it is made of a transparent material that can refract and focus light. When you hold the stem over a scale, it magnifies the divisions on the scale, making it easier to read the temperature.
Who element used of the glass tube of clinical thermometer to measure thermometer?
mercury
Why is the glass stem of a thermometer designed to act like a magnifying glass?
The glass stem of a thermometer is not designed to act like a magnifying glass. Its purpose is to contain the temperature-sensitive liquid or metal that expands or contracts with temperature changes to provide a reading on the thermometer scale. Magnifying glasses have a different purpose of magnifying objects placed beneath them.
Why is the stem of a thermometer designed like a magnifying glass?
So you can read it more easily.
Why is the glass stem on a clinical thermometer designed to act like a magnifying glass?
The stem of the thermometer is not perfectly round for two reasons. One so it will not roll off and fall, and two, the flat area acts as a magnifying glass to make the hollow shaft in the stem appear larger.
What is a glass bulb of a thermometer?
A glass bulb of a thermometer is the part at the bottom of the thermometer that contains mercury or colored alcohol that expands and contracts with temperature changes. This expansion and contraction of the liquid is what causes the thermometer to measure and display the temperature.
Why is a stem of a thermometer glass and why is it designed this way?
The stem of a thermometer is typically made of glass to withstand temperature changes and allow for easy reading of the temperature scale. The design of the stem helps to ensure accurate measurement of temperature by allowing the expansion and contraction of the liquid inside without breaking the glass. It also provides a clear pathway for the liquid to rise or fall in response to temperature changes.
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 difference between a stem thermometer and a candy thermometer?
A stem thermometer is used to measure the internal temperatures of foods, especially meats. Stem thermometers have a "stem" that is inserted into the food and a flat round "face" at the top that may be digital or dail. Candy thermometers are used to measure the heat of candy while it is cooking. They are large straight tubes similar to thermometers used to take body temperature. They have a clip that enables the cook to clip it to the pan.
