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 thermometer in laboratory?

Laboratory thermometers measure temperature with a high level of precision for applications such as experiment monitoring instrument calibration materials testing and maintaining a sterile work environment.

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.

Where are thermometers used?

Oral: For this method the thermometer is placed under the tongue. This method is used for adults and children 4 and over who are able to hold thermometer in mouth. Rectal: For this method the thermometer is inserted gently into the rectum. This is mostly done in babies but can used in children up to 3 years of age.

What are 2 important things that he does upon using thermometer?

A thermometer has two important elements: (1) a temperature sensor (e.g. the bulb of a mercury-in-glass thermometer or the pyrometric sensor in an infrared thermometer) in which some change occurs with a change in temperature and (2) some means of converting this change into a numerical value (e.g. the visible scale …

How does a thermometer help meteorologists?

Thermometer. Temperature changes forecast weather events. Thermometers measure the changes in the temperature by using a liquid such as mercury or alcohol normally colored red. … Some thermometers called spring thermometers measure the expansion and retraction of metal to measure the temperature.

How does a body thermometer work?

Digital thermometers work by using heat sensors that determine body temperature. They can be used to take temperature readings in the mouth rectum or armpit. When assessing digital thermometer readings keep in mind that armpit (axillary) temperature runs about ½ to 1°F (0.6°C) cooler than oral readings.

What temp is a fever?

The following thermometer readings generally indicate a fever: Rectal ear or temporal artery temperature of 100.4 (38 C) or higher. Oral temperature of 100 F (37.8 C) or higher. Armpit temperature of 99 F (37.2 C) or higher.

What is the purpose of the thermometer in simple distillation?

In the top of this connector is the thermometer which is used to read the temperature of the vapor just as it condenses. The temperature reading is important because at normal conditions the temperature of the vapor passing through is the same as the boiling point of the substance being collected.

Why is it important to know how do you use thermometer?

Measuring body temperature is very important in medicine. A number of diseases are characterised by a change in body temperature. With other illnesses the course of the disease can be followed by measuring body temperature. This allows the doctor to analyse the effectiveness of treatments based on body temperatures.

How is a thermometer used to study weather?

A THERMOMETER measures the air temperature. Most thermometers are closed glass tubes containing liquids such as alcohol or mercury. When air around the tube heats the liquid the liquid expands and moves up the tube. A scale then shows what the actual temperature is.

How does a thermometer measure body temperature?

Axillary method (under the armpit)
  1. Place the tip of the thermometer in the centre of the armpit.
  2. Tuck your child’s arm snugly (closely) against their body.
  3. Leave the thermometer in place for about 1 minute until you hear the “beep”
  4. Remove the thermometer and read the temperature.

What is your normal body temperature?

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). A temperature over 100.4°F (38°C) most often means you have a fever caused by an infection or illness.

What is the working principle of digital thermometer?

Digital thermometers contain a small computing mechanism and a resistor. A change in temperature causes the sensor to notice a change in resistance. The computer converts the difference in resistance into a difference in temperature and offers a digital readout in degrees.
