Where are the laboratory thermometer commonly used?

Laboratory thermometers are used in research and scientific applications such as monitoring experiments, maintaining a sterile work environment, calibrating other laboratory instruments, and testing materials.

Why do we use laboratory thermometer?

A laboratory thermometer is used to measure the boiling point and freezing point during science experiments. It is also used to measure the temperature of substances. It measures temperature ranging between -10 degree Celsius and 110 degree Celsius.

Why mercury thermometer is used in laboratory?

Mercury is the only one in liquid state at room temperature. It’s used in thermometers because it has high coefficient of expansion. It also has a high boiling point which makes it very suitable to measure higher temperatures. Also, it has a shiny appearance and doesn’t stick to the glass surface of glass.

What is laboratory 7th thermometer?

 A laboratory thermometer is used to measure temperatures or the temperature changes of other objects.  These thermometers are usually filled with red spirit rather than mercury.  The range of a laboratory thermometer is generally from −10°C to 110°C.

Is mercury used in laboratory thermometer?

Mercury thermometers can be used to determine body, liquid, and vapor temperature. Mercury thermometers are used in households, laboratory experiments, and industrial applications.

Does laboratory thermometer have mercury?

Laboratory thermometers A laboratory thermometer has a long stem with a silver bulb at the end. The silver color in the bulb usually means there is mercury in it. Mercury becomes bigger as the temperature becomes hotter. But mercury is a poison to humans.

How many types of laboratory thermometers are there?

The common types of laboratory thermometers include liquid-in-glass, bimetallic strip, infrared, and electronic devices. The common types of clinical thermometers are digital, disposable, glass and mercury, electronic ear, and forehead devices.

Why alcohol is used in laboratory thermometer?

Alcohol is used in a laboratory thermometer instead of a clinical thermometer because alcohol has a very low freezing point in comparison to the Mercury. It is used in a cool place or region. The freezing point is the temperature at which a liquid starts changing into solid-state.

Why clinical thermometer is not used in laboratory?

Working of a Clinical Thermometer A clinical thermometer cannot be used to measure high temperatures because it has been designed to measure only human body temperature which varies over a short range. If a clinical thermometer is used to measure high temperatures, it will get damaged.

What are the uses of thermometer?

Uses of a Clinical Thermometer. Traditional thermometers use thermometric liquids (i.e., alcohol, mercury) to measure temperature in body cavities — orally, rectally, vaginally — or at other axillary points, such as the underarm. Many newer thermometers use infrared radiation to record temperature at alternative points, such as the eardrum (tympanic) or forehead.

What is thermometer used for in chemistry?

A thermometer is used to measure the temperature of different materials or substances. It can be used for solids, liquids or even gases. A typical thermometer contains a liquid solution inside, which is often mercury.

How do thermometers measure temperature?

A thermometer measures the temperature of things. “Thermo” means heat, and “meter” means to measure. A thermometer is capable of measuring the temperature of a wide range of objects and the temperatures of individuals. These measurements include body temperature, oven temperature and outside temperature.

What is the purpose of a thermometer?

A thermometer is used in health care to measure and monitor body temperature. In an office, hospital or other health care facility, it allows a caregiver to record a baseline temperature when a patient is admitted.
