What is the boiling point of mercury is?

674.1°F (356.7°C)
Mercury/Boiling point

Mercury is silvery white, slowly tarnishes in moist air, and freezes into a soft solid like tin or lead at −38.83 °C (−37.89 °F). It boils at 356.62 °C (673.91 °F).

How much more is the boiling point of mercury than water?

Mercury’s atomic number is 80 and its atomic weight is 200.59. It has a boiling point of 674°F (356.7°C) and a melting point of -38°F (-38.89°C). Mercury is stable (it does not react) in air and water, as well as in acids and alkalis. The surface tension of mercury is six times higher than that of water.

What is the boiling point of mercury at atmospheric pressure?

357°C.
Boiling point of Mercury is 357°C. Note that these points are associated with the standard atmospheric pressure. In thermodynamics, saturation defines a condition in which a mixture of vapor and liquid can exist together at a given temperature and pressure.

Is the boiling point of mercury lower than that of alcohol?

The contents of alcohol are less toxic and will evaporate quickly as compared to the mercury-in-glass thermometer. Since, alcohol starts boiling at 80℃ while the boiling point of mercury is 375℃. Therefore, a mercury thermometer is used to measure high temperatures.

What is boiling point and melting point of mercury?

Mercury has a melting point of -38.9oC, a boiling point of 356.7oC, and is the only metal to remain in liquid form at room temperature. Droplets of liquid mercury are shiny and silver-white with a high surface tension, appearing rounded when on flat surfaces.

What’s the melting point of mercury?

-37.89°F (-38.83°C)
Mercury/Melting point

How much does mercury expand when heated?

Mercury’s volume coefficient of expansion is 0.00018, so it expands by . 018 percent in volume for every degree of temperature increase. To make the difference easier to see, a mercury thermometer contains a reservoir of the metal and a thin glass capillary into which it can expand.

What’s the melting point of Mercury?

What is melting point and boiling point of mercury?

Can mercury thermometer measure?

In a mercury thermometer, a glass tube is filled with mercury and a standard temperature scale is marked on the tube. With changes in temperature, the mercury expands and contracts, and the temperature can be read from the scale. Mercury thermometers can be used to determine body, liquid, and vapor temperature.

Why is mercury thermometer more accurate than alcohol thermometer?

It is more durable than alcohol thermometer because mercury does not evaporate easily. It is smaller in size as compared to alcohol one. Mercury does not wet the wall of the thermometer, which means that results can be highly accurate.

What is the melting and boiling point of mercury?

It has a boiling point of 674°F (356.7°C) and a melting point of -38°F (-38.89°C). Mercury is stable (it does not react) in air and water, as well as in acids and alkalis.

How do you measure boiling point with a thermometer?

How do you measure boiling point? 1 put a boiling stone in the mini test tube. 2 add about 1/2 inch of liquid. 3 clamp in stand in the fume hood. 4 insert thermometer into test tube with bottom of mercury bulb about 1/2 – 1 inch above the liquid. 5 carefully heat with mini bunsen burner till temperature remains constant. 6 read temperature.

Why was Mercury used to measure the temperature of water?

With mercury as the measuring fluid, temperatures could be recorded well above water’s boiling point and below its freezing point. Using mercury also allowed the degrees to be marked more accurately in finer subdivisions.

What are the physical properties of mercury?

Properties Of Mercury. Mercury’s atomic number is 80 and its atomic weight is 200.59. It has a boiling point of 674°F (356.7°C) and a melting point of -38°F (-38.89°C).
