Usually Mercury Is Used As Thermometric Liquid In Thermometer Because

Question

Mercury has several properties that make it ideal for use as a thermometric liquid. For example:

It has high density.

Mercury is the densest liquid metal. It has a density of 13.5 g/cm3, which makes it ideal for thermometers and barometers. Because mercury can expand when heated, its use in these instruments allows them to measure temperature changes more accurately than other materials would allow.

It has low viscosity.

Viscosity is a measure of how thick a liquid is. It depends on the force needed to push the liquid, and can be thought of as the internal friction that resists flow. The viscosity of mercury is low because it has such a high density (13 g/cm3), which means there are many atoms packed into each cm3 of space. This makes it hard for them to move past one another when they’re forced together at high speeds, which results in less viscosity than other liquids like water or alcohols have at room temperature.

It is a good conductor of heat and electricity.

Mercury is a good conductor of heat and electricity. It is also a liquid metal with a high boiling point, which makes it ideal for use in thermometers.

When you feel hot or cold, your body makes adjustments to keep its internal temperature at 98.6 degrees Fahrenheit (37 degrees Celsius). If you get too hot, the blood vessels near the surface expand so that there is more room for heat to escape; if you get too cold, they contract so that less blood flows through them and therefore less heat escapes from your body’s core. Mercury does something similar when used in thermometers: When heated up or cooled down by contact with another substance such as water or ice cream (which acts like an insulator), it expands or contracts accordingly–and thus changes shape slightly–so that its meniscus moves up or down on the inside of tube containing it

The coefficient of expansion of mercury is nearly constant at all temperatures from 0 to 400 C.

The coefficient of expansion is the change in volume per degree change in temperature. The coefficient of expansion of mercury is nearly constant at all temperatures from 0 to 400 C and equal to 12.5 x 10^-6 (1/10^6).

Mercury is not attacked by most acids and alkalies except hot concentrated sulphuric acid, which dissolves it completely in about one hour at room temperature, or in a few minutes when boiling hot. It does not react with ammonia even when heated strongly, but some organic compounds containing amines attack it vigorously.

Mercury dissolves in nitric acid with evolution of heat, forming a dark red solution known as “corrosive sublimate” which oxidizes many metals by dissolving them first; the action stops if the solution cools down or if bromine is added to stop oxidation further (it reacts very slowly with mercury), but it can be safely used in dilute form to clean metallic surface of grease etc; it also forms complex salts with many metals, such as silver nitrate (AgNO3) and gold chloride (AuCl).

Mercury has many properties that make it ideal for thermometers, but there are some downsides

Mercury has many properties that make it ideal for thermometers. It is a liquid at room temperature, which means that its density can be easily measured by comparing the heights of two columns of mercury with different amounts of mass.

Mercury is also a good conductor of heat and electricity, so it provides an accurate reading even when large amounts of heat are being transferred from one object to another (like in your car). In addition to these benefits, mercury does not react with most acids or alkalies–this means that you won’t have any issues if you spill some on your carpet!

    Usually Mercury Is Used As Thermometric Liquid In Thermometer Because

    Mercury is a liquid metal that has several applications in thermometry. Usually, mercury is used as a thermometric liquid in thermometers because it is non-toxic, inexpensive, and has a wide range of uses. In this blog post, we will explore the different types of mercury and how it can be used in thermometry. We will also discuss some of the safety concerns associated with using mercury in thermometers.

    What is Mercury?

    Mercury is a liquid metal that is often used as a thermometric liquid in thermometers because it maintains a constant temperature even when the surrounding environment changes.

    How is Mercury Used in Thermometers?

    Mercury is a liquid element that is used in thermometers because it is a good thermometric material. Mercury has a very low temperature coefficient, meaning that it doesn’t change its heat capacity as its temperature changes. This makes mercury an ideal material for use in thermometers because the changing temperature of the mercury doesn’t affect the measurement of the temperature.

    Health Risks Associated with Mercury in Thermometers

    There are health risks associated with mercury in thermometers. Mercury can damage the nervous system, reproductive system, and kidneys. It can also cause cancer. There are now thermometers that use other substances to measure temperature, such as digital sensors or infrared technology.

    How to Avoid Mercury in Thermometers

    There are many ways to avoid mercury in thermometers, but the most common is to not use them to measure temperatures above the boiling point of mercury.

    Mercury has been used in thermometers since the 1600s. Measurement of temperature by mercury dates back to at least the 4th century AD, when scientists used it to measure the temperature of blacksmiths’ forges. Mercury is still widely used today because it has several unique properties that make it ideal for use as a thermometric liquid.

    Mercury has a very low coefficient of thermal expansion.

    The coefficient of thermal expansion is the amount that the length of a material changes as its temperature changes. Mercury has a very low coefficient of thermal expansion, which means that it does not change in length as easily as other liquids. This makes mercury thermometers more accurate than other types of thermometers, since they won’t need to be readjusted for different temperatures.

    Mercury has a high index of refraction.

    The index of refraction is a measure of how much light is bent when passing from one medium to another. The higher the index, the more light is bent.

    Mercury has an index of refraction of around 1.52–it’s quite a bit higher than water or air (which have indices around 1).

    Mercury is relatively non-corrosive and non-toxic.

    Mercury is a liquid at room temperature and has a density similar to that of water. It is therefore used as a thermometric liquid in thermometers because it expands uniformly with temperature changes, unlike some other liquids.

    Mercury has been known since ancient times, but its toxicity was not recognized until the 18th century. Mercury is still used in some medical devices such as sphygmomanometers (blood pressure monitors) and barometers, although these applications have declined due to mercury’s toxicity being well-known by then.[1] The name mercury comes from Latin hydrargyrum (“water silver”).

    Mercury has a high density and is thus a heavy liquid.

    Mercury has a high density and is thus a heavy liquid. The density of mercury is 13.6 g/cm3, which is more than twice the density of water (1 g/cm3). This makes it ideal for use in thermometers because it will sink down towards cold temperatures rather than float up like other liquids would do.

    Takeaway:

    As you can see, mercury is a thermometric liquid. It is used as thermometric liquid in thermometer because of its properties which make it very suitable for this purpose. Mercury has a very low coefficient of thermal expansion and high boiling point, so it does not change much when heated or cooled.

    Mercury is the most popular thermometric liquid used in thermometers. The reasons for its popularity are: -Low coefficient of thermal expansion

    -High boiling point

    -High density at room temperature
