Mercury and Alcohol are used in the thermometer because they remain in liquid form with temperature change . Even a small change in temperature changes the volume of the Alcohol or Mercury. By calculating the expansion of the liquid, the temperature is measured.
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.
The correct answer is Mercury. Mercury is used in thermometers because it remains in liquid form throughout a wide range of temperatures i.e -37.89 degrees Fahrenheit to 674.06 degrees Fahrenheit.
Temperature is a degree of hotness or coldness the can be measured using a thermometer. It's also a measure of how fast the atoms and molecules of a substance are moving . Temperature is measured in degrees on the Fahrenheit, Celsius, and Kelvin scales.
Mercury is the only one in liquid state at room temperature. It's used in thermometers because it has high coefficient of expansion . Hence, the slightest change in temperature is notable when it's used in a thermometer. It also has a high boiling point which makes it very suitable to measure higher temperatures.
Although many liquids could be used in pressure measuring devices, mercury is used because its high density requires less space . It is also a good conductor of electricity, so it is a useful component of electrical switches. Mercury is also used in dental fillings, paints, soaps, batteries, and fluorescent lighting.
A thermometer is an instrument for measuring or showing temperature (how hot or cold something is). One type of thermometer is a narrow, concealed glass tube containing mercury or alcohol which extends along the tube as it expands.
A thermometer is an instrument that measures temperature . It can measure the temperature of a solid such as food, a liquid such as water, or a gas such as air. The three most common units of measurement for temperature are Celsius, Fahrenheit, and kelvin. The Celsius scale is part of the metric system.May 19, 2022
Thermometers are used in the House It is also used to check the temperature of grill stands, ovens and other heating appliances before reuse. An Infrared thermometer is used in this case in order to get a fast and accurate reading.
- To measure the outdoor temperature . - To measure body temperature during a physical exam at the doctors. - To measure body temperature when someone is ill to determine if he/she has a fever. - To measure the temperature of an oven.
The different types of medical thermometers
Thermometer is a device which is used to measure temperature . Thermometer is made of a long narrow glass tube, with a bulb at one end. The narrow tube appears as a continuous silver line, because it is filled with mercury.
THERMOMETER. Thermometer is the standard instrument used to measure temperature of an object . It is the most trusted way to measure temperature.it is used in the hospital, laboratory, and weather station and so on. The human normal body temperature is 37.0°C or about 98.6 °F. TYPES OF THERMOMETER.
