What is the advantages of mercury as a thermometric substance?
Mercury has a wide temperature range, high thermal conductivity, and a linear expansion coefficient, making it suitable for precise temperature measurements. Additionally, it does not wet the glass surface, allowing for accurate readings.
When A (ordinary) glass bottle is filled to the brim with mercury. If the temperature of both the bottle and mercury are increased by 19.3oC what fraction of the mercury will spill out of the bottle?
When the temperature of the glass bottle and mercury increases, the volume of both also increases. However, since mercury has a greater coefficient of volume expansion than the glass, it will expand more, causing it to spill out of the bottle. The fraction that will spill out can be calculated using the coefficients of volume expansion for mercury and glass, along with the initial volume of mercury and bottle.
Why is mercury preferably used in a thermometer when compared to alchol?
Mercury has a higher coefficient of expansion than alcohol, allowing for a more sensitive temperature reading. It also remains a liquid at a larger range of temperatures, making it suitable for measuring both high and low temperatures accurately. Additionally, mercury does not wet its container, ensuring a clear and consistent meniscus in the thermometer.
What is the purpose of Mercury in a Thermometer?
Mercury in a thermometer is used because it has a high coefficient of expansion, meaning it expands and contracts in response to temperature changes. This property allows for accurate measurement of temperature as the mercury level rises and falls inside the thermometer. Additionally, mercury has a wide temperature range in which it remains a liquid, making it suitable for measuring a broad range of temperatures.
Why is Mercury used in thermometers instead of alcohol?
Mercury thermometers have advantages over alcohol thermometers. The liquid is visible making the results easy to read. It expands at a regular interval. It measures temperature quickly and accurately.
Can we measure the coefficient of viscosity of mercury by using stoke s law?
Yes, the coefficient of viscosity for Mercury can be calculated using Stoke's Law.
Who discovered mercury metal?
Antoine Laovoisier , prit
What are Antoine Coefficient for H2S?
The Nation Institute of Standards and Technology web site has the figures Note there are three coefficients - the Antoine equation gives a reasonable fit to vapour pressure.
What is the coefficient of linear expansion of mercury?
-39 degrees celsius to 450 degrees celsius
Does mercury have the highest coefficient of volume expansion known?
Yes, mercury has one of the highest coefficients of volume expansion known among common substances. Its coefficient of volume expansion is approximately 181 x 10^-6 per degree Celsius.
What liquid metal is most commonly used in thermometer?
The liquid metal in many thermometer is mercury (Hg).
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.
Why did Antoine lavoisier collect hydrogen chloride gas by displacement of mercury?
Antoine Lavoisier collected hydrogen chloride gas by displacement of mercury in order to obtain a pure sample of the gas for further study and analysis. The method allowed him to separate and collect the gas without it reacting with the atmosphere or other components present in the reaction.
How did Antoine Lavoisier recognized hydrogen?
he, like found it in a suit case with like Zacharaist and stuff

When a mercury therometer is heated the mercury expands and rises in the thin tube of glass What does this indicate about the relative rates of expansion for mercury and glass?
The fact that the mercury expands and rises in the thin glass tube when heated indicates that mercury expands more than glass when heated. This suggests that mercury has a higher coefficient of thermal expansion compared to glass.
Would a common mercury thermometer be feasible if glass and mercury expanded at the same rates for changes in temperature?
No, even if glass and mercury expanded at the same rates, a common mercury thermometer would not be feasible because the volume of mercury would still change non-linearly with temperature due to its high thermal expansion coefficient. This would result in inaccurate temperature measurements.
