What is laboratory thermometer short answer 7?
Laboratory or Lab thermometers are the instruments that are used to measure the temperatures for scientific researches in schools and labs. Lab thermometers are designed to measure the temperatures, the boiling point and the freezing point of substances.
Laboratory thermometers are designed to measure the temperatures of objects around us and not for measuring human body temperature. The range of a laboratory thermometer is -10°C to 110°C. Hence, it can measure readings even below 0°C till -10°C. It can also measure the temperature of 100°C.
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 range from 35˚C to 42˚C.
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.
A laboratory thermometer is used for measuring temperatures other than the human body temperature. They can measure temperatures from -10˚C to 110˚C. Laboratory thermometers are designed for experimental purposes such as checking boiling point, freezing point, or temperature of other substances.
To measure the temperature a person has to hold the tip of the thermometer either under the armpit or in the mouth under his tongue for a minute. Then we observe the number against the point at which the mercury column stop rising further. This number indicates the body temperature of the person.
A lab thermometer can't be used to measure body temperature as it does not have a kink. The kink, in a clinical thermometer, prevents mercury levels from falling on its own so that temperature can be read even when the thermometer is no longer in contact with our body.
A thermometer is an instrument which is used to measure the temperature of a substance. It is a measure of how excited the molecules of a substance are.
Thermometers may contain a fluid such as mercury or a gas in a glass or metal tube. In the case of liquid-in-glass thermometers, the liquid expands as the temperature rises, indicating the temperature.
- Clean the tip with cold water and soap, then rinse it.
- Turn the thermometer on.
- Put the tip under your tongue, towards the back of your mouth.
- Close your lips around the thermometer.
- Wait until it beeps or flashes.
- Check the temperature on the display.
How do you use a thermometer correctly?
Place the thermometer tip under your tongue. Close your mouth around the thermometer for the recommended amount of time or until the thermometer beep indicates it's done. Remove the thermometer and read the number.
When the tip of the mercury thermometer touches the material it is measuring, the material conducts heat energy to the mercury. Then the mercury expands as it turns into a liquid and begins to rise up the tube. The place where the mercury stops on the scale is where you can take the reading of the temperature.
