Question

What is the 3 types of temperature mesuared in the thermometer.​

Answer 1

The three most common units of measurement for temperature are Celsius, Fahrenheit, and kelvin. The Celsius scale is part of the metric system.

Answer 2

Answer:

Fahrenheit

• The Fahrenheit scale is a temperature scale based on one proposed in 1724 by the physicist Daniel Gabriel Fahrenheit. It uses the degree Fahrenheit as the unit

Celsius

• 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.

Kelvin

• The kelvin is a base SI unit of measurement, defined as the fraction 1/273.16 of the temperature of the triple point of water, which is the temperature at which water in solid, liquid, and gaseous state coexist in equilibrium.

✯Thermometer

Thermometer (thermos: hot; metron: measure) is the universal instrument used to measure temperature. Temperature and heat are two words that often confuse people.

✯Temperature & Thermometer

By definition, the temperature is the measurable extent of hotness or coldness. It is a mathematical representation of heat. There are different units to measure temperatures, like Celsius (˚C), Kelvin (K), and Fahrenheit (˚F).

There are different types of thermometers according to their needs. For example, there is one set of thermometers that are used to measure body temperature while another set of thermometers to measure boiling point and freezing point during experiments. Here, we will discuss the two types of thermometers, namely, clinical thermometer and laboratory thermometer.

✯Properties of thermometric liquid

The liquid that is used in the thermometer needs to have some properties, and they are listed below:

• The liquid used should be visible.

• The thermal expansion of the liquid must be uniform.

• The freezing point of the liquid used must be low.

✯Clinical Thermometer

Clinical thermometers are meant for clinical purposes. It is developed for measuring the human body temperature. It is a long narrow glass tube with a bulb containing mercury at the end. The normal human body temperature is 37˚C; which can fluctuate between the ranges 35˚C to 42˚C. Hence, the clinical thermometers have the range 35˚C to 42˚C. The level of mercury tells our body temperature in ˚C. Since mercury is a toxic element, thus these thermometers have been replaced by digital thermometers nowadays.

Note: Clinical thermometers must be sterilized before use for the safe and clean check-up.

✯Laboratory Thermometer

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. Laboratory thermometers are designed for lab purposes such as checking boiling point, freezing point, or temperature of other substances. You can use a laboratory thermometer for checking the temperature of a solvent but not a clinical one.

Weather reporters also use maximum-minimum thermometers for measuring maximum and minimum temperatures of a place.

✯Uses of Thermometer

Some applications and uses of thermometer is given below :

• In the House
• In automobiles
• In industries
• In restaurants

☆Thermometers are used in the House

A thermometer comes in handy when you need to know the temperature of objects to prevent from burn injuries for ensuring safety of people in the family, especially children. It

☆It is also used in Automobiles

Infrared thermometers are designed to take readings from a distance so, when you are working on your automobile and having a hard time reaching the wires, hose and other equipment, this thermometer can prove beneficial in this situation.

☆Uses of thermometer in Industries

In some industries, it is very important to check for air leaks and poorly insulated areas to ensure safety standards are maintained.

Clinical and laboratory thermometer are used in in medical and scientific industries. Similarly, if there is a cold area near the exit or doorways, then it means heat is lost.

☆Thermometers are used in Restaurants

Big restaurants use thermometers to keep track of the oil and dish’s temperature to achieve perfection and customer satisfaction.
