What does meter mean in thermometer?
Thermometers are used to see if you have a fever or tell you how cold it is outside. Made up of thermo (heat) and meter (measuring device), the meaning of the word thermometer is pretty straightforward.
Which Metre is used in thermometer?
The metric system, including Celsius, is the official system of measurement for almost all countries in the world. Most scientific fields measure temperature using the Celsius scale. Zero degrees Celsius is the freezing point of water, and 100 degrees Celsius is the boiling point of water.
How do you use a temperature meter?
Place the protective cover on the tip of the thermometer. Gently insert the thermometer until the ear canal is fully sealed off. Press and hold down the button for 1-2 seconds until you hear a beep (follow the manufacturer’s instructions). Remove the thermometer, discard the cover, and record temperature and time.
What does meter mean as a root word?
Science. The root metr/meter as in metric means “measurement.” The root therm as in thermos means “heat.” In each of the following key words, underline the root. Using ROOT CLUES. The roots metr/meter (measurement) and therm (heat) give you clues about meaning.
What does Celsius mean in weather?
Celsius, also called centigrade, scale based on 0° for the freezing point of water and 100° for the boiling point of water. Invented in 1742 by the Swedish astronomer Anders Celsius, it is sometimes called the centigrade scale because of the 100-degree interval between the defined points.
Why is a metre a metre?
The metre was originally defined in 1793 as one ten-millionth of the distance from the equator to the North Pole along a great circle, so the Earth’s circumference is approximately 40000 km. In 1799, the metre was redefined in terms of a prototype metre bar (the actual bar used was changed in 1889).
How is a thermometer used to measure temperature?
Learn more about thermometers, heat energy, and temperature with BYJU’S engaging video lectures. These thermometers are used for measuring the temperature by the means of an electronic circuit. The information captured is sent to a microchip that processes it and gets displayed numerically on the digital screen.
What kind of thermometer can you use other than the human body?
Since clinical thermometers can’t be used to measure temperature other than the human body, we need a special type of thermometers for other purposes. A laboratory thermometer, which is colloquially known as the lab thermometer, is used for measuring temperatures other than the human body temperature. It ranges from -10˚C to 110˚C.
What happens when a thermometer is exposed to the air?
When a thermometer is exposed to the atmosphere, the surrounding air’s temperature will permeate it, eventually balancing the thermometer’s temperature with its own—a process whose fancy scientific name is “thermodynamic equilibrium.”
Can a liquid thermometer measure the temperature of alcohol?
Liquid thermometers can be limited by the type of liquid used. Mercury, for instance, becomes a solid at -38.83 degrees Celsius (-37.89 degrees Fahrenheit). Mercury thermometers cannot measure temperatures below this point. Alcohols, such as ethanol, boil at about 78 degrees Celsius (172 degrees Fahrenheit).
