The liquid metal in many thermometer is mercury (Hg).
Mercury is a liquid metal used in thermometers. However, it becomes a solid at -37.9 F and it can cause mercury poisoning if ingested or inhaled. Therefore, most theremometers use ethyl-alcohol or a plastic strip covered with liquid crystals (called a liquid crystal thermometer).
Mercury (Hg) because it is the only metal which is a liquid at room temperature and conducts heat well. It also has a large range (-39 to 357 oC).However, mercury is rarely used in thermometers today, due to its toxicity. If you come across a liquid metal thermometer, it is most probably one containing an alloy of indium, gallium and tin.
what are the sulfide mineral used to a thermometer
Which thermometer is most suitable for measuring boiling point of water mercury or alcoholic thermometer
Yes, a laboratory thermometer can be used to measure the temperature of a room, as it is designed to provide accurate temperature readings. However, it may not be the most practical choice for room temperature measurement due to its sensitivity and the time it may take to stabilize. Typically, a simpler thermometer, such as a digital or mercury thermometer, is more commonly used for this purpose. Always ensure that the thermometer is placed away from direct sunlight or drafts for an accurate reading.
mercury
A thermometer is most commonly used to measure the temperature of a liquid. Other methods, such as infrared thermometers or thermocouples, can also be used depending on the specific application and characteristics of the liquid.
Most commonly a thermometer.
Actually anything that won't freeze or boil at the operating range of the thermometer. The most common are mercury and alcohol.

expand
alcohol, such as ethanol or dyed ethyl alcohol. Mercury and alcohol are both used in thermometers due to their ability to expand and contract with temperature changes, allowing accurate measurement of thermal fluctuations. Mercury is less common now due to its toxicity.
Most of the liquid in a thermometer is typically found in the bulb at the bottom of the thermometer. This is where the temperature changes cause the liquid to expand or contract, moving up or down the tube to indicate the temperature.
Most thermometers contain either mercury or alcohol as the liquid metal. Mercury thermometers are being phased out due to the toxicity of mercury. Alcohol-based thermometers are safer and more environmentally friendly.
Water is most commonly found in its liquid form.

A thermometer utilizes the fact that most liquids expand when heated. As the temperature of the liquid inside the thermometer increases, its volume expands, causing the liquid to rise within the narrow tube of the thermometer and indicating a higher temperature reading.
