Mercury is considered an ideal thermometric liquid because it has a wide temperature range over which it remains a liquid, from -39°C to 356°C. It also has a high thermal conductivity, making it respond quickly to temperature changes. Additionally, it has a uniform coefficient of expansion, leading to consistent and accurate temperature measurements.

What is a liquid metal that expands and contracts as the temperature changes and is the metal used in thermometers called?
The liquid metal used in thermometers that expands and contracts as temperature changes is mercury. Mercury is commonly used due to its unique properties, such as its wide liquid temperature range and high thermal conductivity, making it ideal for accurate temperature measurement.
What property of mercury makes it different from other metals and also make it useful in thermometers and silent lights?
Mercury is unique in that it is a liquid at room temperature, unlike most other metals which are solid. This property allows it to expand evenly when heated, making it ideal for use in thermometers. In addition, mercury's high density and low reactivity make it useful in silent lights, where it conducts electricity and generates light without creating noise.
Why mercury can be used in a thermometer but silver cannot?
Mercury has a high coefficient of expansion, allowing it to rise and fall uniformly in the thermometer tube. Silver, on the other hand, lacks this property and would not provide accurate temperature readings. Additionally, mercury remains in liquid form in a wide range of temperatures, making it ideal for use in thermometers.
What is the ideal absolute liquid ratio?
[1: 2] Absolute liquid assets take into account cash in hand, cash at bank, and marketable securities or temporary investments. The most favourable and optimum value for this ratio should be 1: 2. It indicates the adequacy of the 50% worth absolute liquid assets to pay the 100 percent worth current liabilities in time.

How can Mercury be used as a liquid in a thermometer?
Mercury is a good thermal conductor and has a wide range of temperature stability, making it suitable for use in thermometers. It expands and contracts evenly with temperature changes, allowing for accurate readings. It remains in liquid form across a wide temperature range, making it ideal for use in both high and low temperature environments.
What is a liquid metal that expands and contracts as the temperature changes and is the metal used in thermometers called?
The liquid metal used in thermometers that expands and contracts as temperature changes is mercury. Mercury is commonly used due to its unique properties, such as its wide liquid temperature range and high thermal conductivity, making it ideal for accurate temperature measurement.
Why a thermometer contain mercury not the other liquid?
Mercury is used in thermometers because it is a good conductor of heat and expands uniformly with temperature changes. This allows for accurate and consistent temperature readings. Additionally, mercury has a wide range of temperature measurement and remains a liquid at room temperature, making it suitable for use in thermometers.
Is a liquid metal used in barometers?
Science and industrial labs often use mercury filled barometers due to mercury's high density and low vapour pressure. This allows the barometers column of liquid to be less than 1 meter high (760 mm Hg=1 atmosphere). As an additional advantage the meniscus of the mercury is upwards at the center, unlike water, making accurate reading simpler. However mercury's toxic attributes make it hazardous if spilled, so mechanical diaphragm barometers are often used.
Why was Mercury used for thermometers?
Mercury is a liquid at room temperature; this made it a useful substance in thermometers. As the mercury heated up, it expanded; this indicated the temperature of the surroundings. Similarly, the colder it got, the more the mercury 'shrunk' so it indicated the low temperature.
What property of mercury makes it different from other metals and also make it useful in thermometers and silent lights?
Mercury is unique in that it is a liquid at room temperature, unlike most other metals which are solid. This property allows it to expand evenly when heated, making it ideal for use in thermometers. In addition, mercury's high density and low reactivity make it useful in silent lights, where it conducts electricity and generates light without creating noise.
Why the mercury is the most used element in many thermometers?
Mercury is commonly used in thermometers because it has a broad liquid temperature range (-39°C to 357°C), a high coefficient of expansion, and is a good conductor of heat. These qualities make it ideal for accurately measuring temperature changes.
Is oxygen considered an ideal gas?
No, oxygen is not considered an ideal gas because it does not perfectly follow the ideal gas law at all temperatures and pressures.
Is CO2 considered an ideal gas?
No, CO2 is not considered an ideal gas because it does not perfectly follow the ideal gas law at all temperatures and pressures.
What should bethe shape of an ideal thermometer?
An ideal thermometer usually has a thin glass tube with a uniform bore, capped at one end with a bulb containing a temperature-sensitive liquid like mercury or alcohol. The tube should have uniform markings along its length for accurate temperature reading. The thin design allows the liquid to expand and contract easily as the temperature changes.
What is scientific reason for using mercury in thermometers?
Mercury is used in thermometers because it has a high thermal expansion coefficient, meaning it expands and contracts significantly with temperature changes. This property allows for accurate measurement of temperature. Additionally, mercury remains a liquid over a wide range of temperatures, making it ideal for use in thermometers.
What kinds of obesity are there?
Twenty to forty percent over ideal weight is considered mildly obese; 40-100% over ideal weight is considered moderately obese; and 100% over ideal weight is considered severely, or morbidly, obese.
