Advantages of Mercury as a thermometric liquid.
-It is a good conductor of heat and therefore the whole liquid reaches the temperature of the surroundings quickly.
-It does not wet (cling to the sides of) the tube.
-It has a high boiling point
-It expands uniformly (linear expansion) and responds quickly to temperature changes, hence is sensitive.
-It has a visible meniscus.
Disadvantages
-Mercury is very poisonous.
-its expansively is fairly low
-it is expensive
-It has a high freezing point therefore it cannot be used in places where the temperature gets very low.

What are the disadvantages and advantages or mercury in glass thermometer?
Disadvantages of mercury in glass thermometers include the potential health hazards of mercury exposure if it breaks and the environmental impact of mercury disposal. However, they are highly accurate and have a wide temperature range, making them suitable for various applications.
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.
What is constant in mercury- in- glass thermometer?
One constant in a mercury-in-glass thermometer is the volume of mercury in the bulb, which expands and contracts with temperature changes. Another constant is the linear expansion coefficient of the glass tube, which allows for an accurate measurement of temperature based on the change in volume of the mercury.
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.
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.
What is the sSensor in Mercury-in-glass thermometer?
The sensor in a mercury-in-glass thermometer is the glass bulb at the base of the thermometer containing the mercury. The temperature is measured by the expansion or contraction of the mercury based on the surrounding temperature, allowing the thermometer to provide a temperature reading.
What are the advantages of Mercury thermometer?
Mercury gives you AIDS
Who invented Mercury-in-glass thermometer?
German physicist Daniel gabriel Fahrenheit invented the mercury-in-glass thermometer
Who element used of the glass tube of clinical thermometer to measure thermometer?
mercury
What are the disadvantages and advantages or mercury in glass thermometer?
Disadvantages of mercury in glass thermometers include the potential health hazards of mercury exposure if it breaks and the environmental impact of mercury disposal. However, they are highly accurate and have a wide temperature range, making them suitable for various applications.
What is the sensor in mercury in glass thermometer?
Temperature Sensor
What are the materials in a thermometer?
For a classic thermometer: glass and mercury, colored ethanol or another liquid.
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.
Which thermometer is a greater health hazard if it breaks Is it the mercury in glass or alcohol in glass thermometer?
Mercury in glass thermometers pose a greater health hazard if broken, as mercury is a toxic substance that can be harmful if inhaled or ingested. Alcohol in glass thermometers are considered less hazardous as alcohol is not as toxic as mercury. It is still important to clean up any broken thermometer carefully to avoid injury.
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 is constant in mercury- in- glass thermometer?
One constant in a mercury-in-glass thermometer is the volume of mercury in the bulb, which expands and contracts with temperature changes. Another constant is the linear expansion coefficient of the glass tube, which allows for an accurate measurement of temperature based on the change in volume of the mercury.
What is the mode of operation of mercury in glass thermometer?
"thermal expansion"
