Detailed explanation-1: -Thermometers are made of glass as glass has a very low coefficient of thermal expansion. Thus when the thermometer undergoes a large temperature change it will have the least change in dimensions for which we will get an accurate reading of the temperature.

Detailed explanation-2: -There is a range of thermometers available for home use, including digital, ear, strip and infrared thermometers. Some thermometers are more suited for specific age groups and situations.

Detailed explanation-3: -Mercury is one of the most familiar materials used in liquid thermometers. Other liquids, such as kerosene or ethanol, may also be used in these types of thermometers. When heat rises, the liquid expands from a bowl or bulb into the empty area, climbing up the tube.
