GeekIsLuv says: To find the temperature of a person, inanimate object, or room. There's a myriad of reasons to measure the temperature -- to find out if you're sick, to determine the comfortability of the room you're in, et cetera.Or it can be used to find how hot or cold something is..and to ensure cooking Temperatures
Mercury. It isn't used much these days in thermometers these days as it is very toxic.
A thermometer measures temperature, indoor or outdoor.
Earth thermometers are used to measure the temperature of the ground or soil at various depths. This information can be important for understanding soil health, agricultural practices, and environmental monitoring. Earth thermometers are particularly useful for studying the temperature profile of the ground over time.

Mercury is the mineral that is traditionally used in thermometers because of its unique properties, such as its high thermal expansion and conductivity. However, due to its toxicity, digital thermometers now use safer alternatives like alcohol or digital sensors.
Some thermometers, known as infrared thermometers or non-contact thermometers, use infrared technology to measure temperature without making physical contact with the object being measured. Traditional thermometers that use mercury or a digital display do not use infrared technology.
When you need them.
Alcohol thermometers use a liquid such as ethanol to measure temperature based on the expansion of the liquid, while digital thermometers use electronic sensors to detect temperature changes and provide a numerical reading. Digital thermometers tend to be more accurate and easier to read than alcohol thermometers.
Doctors use body temperature thermometers to measure body temperature.
You would use a thermometer to measure temperature in a laboratory setting. There are different types of thermometers available, such as digital thermometers, mercury thermometers, and infrared thermometers, each suitable for different applications.

The three main types of thermometers are liquid-in-glass thermometers, digital thermometers, and infrared thermometers. Liquid-in-glass thermometers use a liquid like mercury or alcohol to measure temperature, digital thermometers provide a numeric temperature reading, and infrared thermometers measure temperature from a distance using infrared technology.
Digital thermometers, infrared thermometers, and alcohol or galinstan thermometers are commonly used as alternatives to mercury thermometers due to the environmental and health risks associated with mercury.
Some thermometers use mercury, in these the liquid is silvery. Some thermometers use a red dyed alcohol solutioin.
Achohol, usually. Older thermometers use mercury, but that is too dangerous.
We ca use thermometers, thermocouples, resistance thermometers, pyrometers etc.
