What is a scientific thermometer?

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. Most scientific fields measure temperature using the Celsius scale.

How much does a glass thermometer cost?

All thermometers measure internal body temperature, but the technology now ranges from traditional thermometers to ear thermometers that store past readings and alert users to high fevers. Typical costs: Glass oral thermometers cost between $1 and $15.

Is it illegal to have a mercury thermometer?

Those days have passed. Since 2001, 20 states have banned mercury “fever thermometers” for medical use, and regulations tighten every year. But as of today the federal government has more or less killed the mercury thermometer in the United States—NIST has announced it will no longer calibrate mercury thermometers.

What is inside a laboratory thermometer?

Liquid-in-glass thermometers are made of sealed glass and contain a fluid, usually mercury or red alcohol, whose volume changes relative to its temperature. The liquid expands as the temperature rises, rising in the tube and indicating the temperature.

Who invented thermometer?

The more modern thermometer was invented in 1709 by Daniel Fahrenheit. It was an enclosed glass tube that had a numerical scale, called the Fahrenheit scale. The early version of this thermometer contained alcohol and in 1714 Fahrenheit developed a mercury thermometer using the same scale.

Who uses thermometer?

Meteorologists use thermometers to find out how hot it is or if it’s below freezing. Doctors use thermometers to check your body temperature — a very high or low body temperature means you’re sick.

What is the basic principle of a thermometer?

These liquid thermometers are based on the principal of thermal expansion. When a substance gets hotter, it expands to a greater volume. Nearly all substances exhibit this behavior of thermal expansion. It is the basis of the design and operation of thermometers.

What is range of normal body temp?

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).

Can a smartphone be used as a thermometer?

With the right app, your Android smartphone or tablet can function as a thermometer using your device’s built-in temperature sensor. However, even if your mobile device is not equipped with a temperature sensor, there is still a way to get a decent temperature reading for the surrounding air.

Can you buy mercury thermometers?

While mercury thermometers can measure temperature within one degree Celsius, digital thermometers can be as accurate as 0.001 degrees C a difference of four orders of magnitude in accuracy. This changeover won’t be a big deal for the average person “In fact, you can’t buy [mercury thermometers] anymore,” Strouse said.

Why are glass thermometers not recommended?

Liquid in glass thermometers tend to be fragile and hence easily broken, can only be used where the liquid column is visible, cannot be used for surface temperature measurements, cannot be read from a distance and are unsuitable for high temperature measurements.
