What is a thermometer answer?
A thermometer is a device used for measuring temperature. A thermometer is an instrument that measures temperature. It can measure the temperature of a solid such as food, a liquid such as water, or a gas such as air. The three most common units of measurement for temperature are Celsius, Fahrenheit, and kelvin.
What is thermometer diagram?
Thermometers measure temperatures in degrees, according to either the Celsius or Fahrenheit system. A thermometer measures temperature through a glass tube sealed with mercury that expands or contracts as the temperature rises or falls. As temperatures rise, the mercury-filled bulb expands into the capillary tube.

How do we define temperature?
Temperature is the measure of hotness or coldness expressed in terms of any of several scales, including Fahrenheit and Celsius. Temperature indicates the direction in which heat energy will spontaneously flow—i.e., from a hotter body (one at a higher temperature) to a colder body (one at a lower temperature).
What is thermometer and its types?
A thermometer is a device that is used to measure the temperature of a body. Common types of thermometers are Medical thermometers, Infrared thermometers, Mercury thermometers, thermocouple thermometers, laboratory thermometers, Bimetallic strip thermometers, Pyrometers, etc.
How do you write a thermometer?
Take a reading from a mercury thermometer on a table to find the actual temperature of the room. Write it down next to the line on the bottle. Set the bottle in a container of hot water and label it. Fill the bottom of a container large enough to hold your thermometer with warm water.
What is the use 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.
What is clinical thermometer explain with diagram short answer?
A clinical thermometer is a thermometer used to measure human body temperature. Most made in the 20th century are mercury-in-glass thermometers. They are accurate and sensitive, having a narrow place where the mercury level rises very fast. A kink in the tube stops the mercury level from falling on its own.

What are the features of 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.
What is clinical thermometer explain with diagram Class 7?
It reads temperature from 35°C to 42°C or from 94°F to 108°F. It consists of a long, slender and uniform glass tube with a bulb at one end containing mercury. There is a small shining thread of mercury outside the bulb. There is a kink near the bulb which prevents mercury level from falling on its own.
