mercury thermometer can be used to measure temperature up to

The bulb of the thermometer is immersed into a container filled with pure melting ice. Do not clean up spilled mercury with bare hands. Learn about a little known plugin that tells you if you're getting the best price on Amazon. By means of a maximum thermometer, one can measure the maximum temperature over a predetermined time span. If a mercury thermometer breaks or leaks, it can release toxic vapors. Thallium reduces the freezing point to -78°F (-61.1°C). The first thermometers, however, weren’t thermos or heat measurers, but thermo-scopes, devices that merely signaled whether the temperature was high or low. In order to ensure that the contact between the bulb and ice is good, ice shavings can be used. Historically, mercury thermometers have been used for nearly all temperature measurements because of their accuracy and low cost. This page shows answers for question: Mercury thermometer can be used to measure temperature up to----. The change in the volume of a fixed mass of gas at constant pressure, or the change in pressure of a fixed mass of gas at constant volume, may be used to measure temperature. Mercury can be toxic if consumed, and it can also cause skin and eye damage if touched or respiratory distress if inhaled. Most thermometers hold between 0.02 ounces (0.5 g) and 0.1 ounces (3 g) of mercury. It also has a high boiling point which makes it very suitable to measure higher temperatures. Find right answer with solution and explaination of asked question. This little known plugin reveals the answer. Most modern thermometers are made of much stronger glass then their original counterparts, and the amount of mercury contained in each is quite low in any event. I'm pretty sure I remember when they started phasing out mercury thermometers for at home use. A mercury instrument has been the mainstay of taking temperatures for years. Most modern models work this way, and though advancements have been made in terms of presentation the basics are usually about the same. These thermometers are usually marked with temperature readings on the Fahrenheit or Celsius scale. Maybe I’m not using it properly, I don’t know. At home I’ve taken different temperature readings when using the ear thermometer and got different results each time, usually off by a degree or two – sometimes within the same hour. If you have a mercury thermometer, don't throw it in the trash. Gas thermometers work best at very low temperatures. Carefully read the instructions before using your digital thermometer. A thermometer -- an instrument used to measure air temperature—easily tells us this, but how it tells us is another question entirely. With changes in temperature, the mercury expands and contracts, and the temperature can be read from the scale. I have always preferred mercury thermometers because of how easy they are to use. But mercury thermometers continue to be the most popular. In addition, mercury is the only metal that is a liquid at room temperature, making it an attractive candidate. I really loved the idea of plastic strip thermometers because with mercury thermometers I was always worried about my children dropping the glass vial and breaking it. Medical doctors often use a version known as the maximum mercury thermometer to measure human body temperature. In order to measure temperatures below this point, meteorologists will often mix mercury with thallium alloy. A laboratory thermometer is recognizable by its long stem with a silver bulb at the end. Mercury thermometer can be used to measure temperature up to (a) 260°C (b) 100°C (c) 360°C (d) 500°C Mercury thermometers can be used to determine body, liquid, and vapor temperature. I have found that the digital thermometers that you press against your forehead are absolutely terrible. I am not sure if it was just the brand that was being used on us at work, but it never got a reading correct without multiple tries, and even that final reading was questionable. This is why it can is used to measure body temperature. A laboratory thermometer is a tool used in laboratories to measure temperature with high accuracy. Mercury, which is also sometimes known as quicksilver, is a silvery liquid that responds very well to atmospheric changes, particularly temperature and barometric pressure. There are a number of different model types, sizes, and specifications, but the general operating principle is about the same in all cases. Maximum thermometers are commonly used to measure a person’s body temperature. Thick glass generally encases the temperature-sensitive liquid metal. The basic instrumentality is usually pretty simple. Most digital thermometers are easy to use and measure body temperature within seconds. Laboratory thermometers are designed for lab purposes such as checking boiling point, freezing point, or temperature of other substances. A laboratory thermometer, which is colloquially known as the lab thermometer, is used for measuring temperatures other than the human body temperature. He then developed a system of calibration to create a scale for easy reading. A thermometer is a device that measures temperature or a temperature gradient (the degree of hotness or coldness of an object). Mercury is a dangerous metal. Causes of Mercury used in Thermometer – Mercury thermometers can be used to decide the body, liquid, and vapor temperature. why are glass thermometers rarely used today? Which of the following is not classified as a thermo electric pyrometer? C. Optical pyrometer (disappearing filament type). Note that your temperature is affected by smoking, eating or drinking. usually not no since most clinical thermometers are build to measure human body temperatures which are around 35°C up to 42°C while water boils at 100°C (usual air pressure provided). Therefore, initially, thermometers defined temperatures. Therefore, the mercury thermometer other thermometers accurately measure the temperature of the human body. With the strips you stick on you no longer have to worry about any of that. 6 years ago Once a staple in most medicine cabinets, mercury thermometers use mercury encased in glass to measure body temperature. The thermometer usually has a small reserve of liquid mercury in its base, which is most often pressurized; above it is usually a glass or synthetic tube with a calibrated temperature scale. Many refuse them, preferring electronic ones. read more @allenJo - Ask your doctor what medical thermometer they use. A mercury thermometer is a tool used to measure temperature. Mercury thermometers cover a wide temperature range from −37 to 356 °C (−35 to 673 °F); the instrument's upper temperature range may be extended through the introduction of an inert gas such as nitrogen. These devices weren’t calibrated to a standard scale; they would just make crude or vague assessments.The in… Higher temperatures cause mercury to grow longer, while low temperatures cause it to fall or shrink back down. There may be clinical thermometers which are build for this range but most will not work above 50 … The silver color in the bulb normally indicates the presence of mercury. Colored alcohol or mercury rises along a scale in a bulb thermometer whereas expanding liquid rotates a spring to turn an indicator needle around along a circular scale on a spring thermometer.
