Thermometers are made of materials that can measure and indicate temperature changes. Common thermometer materials include mercury, alcohol, and bi-metal strips. Mercury is used in most traditional thermometers, while alcohol is often found in clinical thermometers. Bi-metal strips are used in inexpensive digital thermometers. The material chosen for a thermometer affects its sensitivity to temperature changes, as well as the maximum and minimum temperatures it can measure. For example, mercury has a much greater range than alcohol, but it is also more sensitive to temperature changes.

What are the different types of thermometers?
There are many different types of thermometers, but all thermometers work by detecting changes in temperature. Some thermometers use mercury to measure temperature, while others use digital sensors.
Here is brief about What Liquid is in a thermometer if it is alcohol or ethanol.
How do mercury thermometers work?
Mercury is a liquid metal that is used in some thermometers to measure temperature. The mercury is placed in a bulb at the bottom of the thermometer, and when the temperature changes, the mercury moves up or down inside the tube. This change in position can be used to calculate the temperature.
Why are mercury thermometers being phased out?
Mercury is a toxic material and can be dangerous if it is released into the environment. For this reason, many countries are working to phase it out.
What is the history of thermometers?
The history of thermometers is long and varied. The first thermometers were created by inventors in the 1600s, and they were made of glass tubes filled with mercury or alcohol. These thermometers were used to measure temperature changes in things like weather and food. In the 1800s, the first digital thermometers were invented. Today, there are many different types of thermometers, including mercury, alcohol, and digital thermometers.
Alcohol is a liquid that is often used in clinical thermometers to measure temperature. When the temperature changes, the alcohol expands or contracts. This change can be used to calculate the temperature. Alcohol thermometers are less sensitive to temperature changes than
What are some common applications for thermometers?
Thermometers are used in a variety of applications, including weather monitoring, cooking, and medical diagnostics. Mercury thermometers are often used to measure air temperature, while alcohol and digital thermometers are commonly used to measure the temperature of food or human bodies.
