What is the function and uses of thermometer?

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. Made up of thermo (heat) and meter (measuring device), the meaning of the word thermometer is pretty straightforward.

What is the function of the thermometer in the experiment?

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.

What are the functions of digital thermometer?

Digital Thermometers A digital thermometer is used to verify a smart temperature transmitter under flowing conditions and a successful calibration of the smart temperature transmitter. Portable electronic thermometers (PETs) are designed to measure temperature in a RTD-type thermowell using a thermistor or RTD probe.

How is a thermometer made?

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. When there is an increase in heat, the liquid inside the bulb expands, pushing up into the tube. A decrease in heat lets the liquid contract, moving down the tube.

How can we use thermometer in our daily life?

– To measure the outdoor temperature. – To measure body temperature during a physical exam at the doctors. – To measure body temperature when someone is ill to determine if he/she has a fever. – To measure the temperature of an oven.

What is the basic principle of 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.

Which material is used in laboratory thermometer?

Mercury is the material used in laboratory thermometer. So it is very easy for us to read the temperature accurately.

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.

Which material is used in digital thermometer?

mercury free
Digital Thermometers are mercury free. These thermometers contain thermistor inside the tip which is used to measure the temperature. They provide quick and highly accurate results over the body temperature range. These thermometers are easy to read with LCD display on them.

What is digital thermometer short answer?

Digital thermometers use a computer chip/heat sensor to tell the temperature instead of mercury. The body whose temperature is to be measured is brought in contact with the thermometer and it recieves heat until it comes at a temperature equal to the temperature of the hot body.

Who invented the doctor’s thermometer?

Sir Thomas Clifford Allbutt (1836–1925) was a celebrated British physician. He spent 20 years working in Leeds during which time he devised the small clinical thermometer.

Why is the thermometer important?

Thermometers are used to measure the temperature and this is a very important part of weather forecasting. The temperature can be read from the scale on the side of the thermometer. Knowing the air temperature is very important. It is an important part of weather forecasting.

What are the functions of the parts of the thermometer?

The available thermometer parts and function have the ability to record temperatures unaided using sensors that record the surrounding conditions. The multifunctional thermometer parts and function are capable of recording heat and humidity changes of the surrounding areas.

What is the purpose of a thermometer?

Thermometers are normally used to measure the temperature of one’s body. This device is traditionally found in clinics, hospitals, pharmacies and homes for this purpose. It helps in recording the temperature of the body at different times, in case of fever caused by various types…

What are the uses of thermometer?

Uses of thermometer. As we established, the main use of thermometer is to measure temperature. You can measure the temperature of many things to get useful information about your surroundings and yourself.

What can a thermometer do?

A thermometer measures heat. With two important elements, the sensor and the reader, a thermometer can measure a physical change in temperature and convert that change into a value that is easily understood.
