What is a simple definition of a thermometer?
: an instrument for determining temperature specifically : one consisting of a sensor housed in a metal probe that registers a change in electrical resistance as a change in temperature.
What is thermometer example?
A thermometer is a tool to measure temperature. Examples include liquid-in-glass thermometers, spring thermometers, industrial gas thermometers, digital thermometers, and liquid crystal thermometers.
What is a thermometer for weather?
Thermometers are used to measure the temperature and this is a very important part of weather forecasting. Many thermometers come in a glass tube that contains a liquid, usually mercury or alcohol. The liquid expands when it’s hotter and contracts when it is colder.
What is thermometer kid definition?
A thermometer is the instrument used to tell the air temperature. A thermometer is usually made up of a small, hollow glass tube. At the bottom of the tube is a bulb, which holds a liquid such as alcohol or mercury.
What’s the correct temperature for a human being?
Normal body temperature varies by person, age, activity, and time of day. The average normal body temperature is generally accepted as 98.6°F (37°C). Some studies have shown that the “normal” body temperature can have a wide range, from 97°F (36.1°C) to 99°F (37.2°C).
What is the thermometer used for?
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.
When should you use a thermometer?
An oral temperature (TEM-per-ah-chur) is when the mouth is used to take your temperature. A temperature measures body heat. A thermometer (ther-MOM-uh-ter) is used to take your temperature in your mouth. A person should be 5 years or older to have a temperature taken in the mouth.
Why are thermometers used?
A thermometer is a tool that measures temperature — how hot or cold something is. Thermometers are used to see if you have a fever or tell you how cold it is outside. Doctors use thermometers to check your body temperature — a very high or low body temperature means you’re sick.
Where does the term thermometer come from and what does it mean?
An apparatus used to measure temperature. Origin: From thermomètre. an instrument for measuring temperature, founded on the principle that changes of temperature in bodies are accompained by proportional changes in their volumes or dimensions
What are the different types of thermometers?
n. An instrument for measuring temperature. An instrument used to measure temperature. There are many types of thermometers; the most common consist of a closed, graduated glass tube in which a liquid expands or contracts as the temperature increases or decreases.
How does an infrared thermometer measure surface temperature?
Just keep reading the article which is going to tell you all about the infrared thermometer. An infrared thermometer is a handheld temperature detecting device which is utilized to measure the surface temperatures of an object or area without having to touch the object.
Can a thermometer be used to measure absolute temperature?
While an individual thermometer is able to measure degrees of hotness, the readings on two thermometers cannot be compared unless they conform to an agreed scale. Today there is an absolute thermodynamic temperature scale.
What is an IR thermometer and what does it do?

What is the function of a thermometer?
A thermometer is a device that measures temperature. Most digital thermometers are resitive thermal devices ( RTD ). RTDs predict change in temperature as a function of electrical resistance.
What do we use a thermometer for?
Environmental Indoor-outdoor thermometer Heat meter uses a thermometer to measure rate of heat flow. Thermostats have used bimetallic strips but digital thermistors have since become popular.
