Oralrectalbaby thermometers containing about 061 grams of mercury.

. Metallic mercury is toxic and also expensive. Why mercury is used in thermometer instead of alcohol. When put under the armpit the mercury in the clinical thermometer therefore becomes warmer and expands.

In addition to the answer and the comment given the use of mercury in thermometers had another advantage frequently used in the lab. Liquid in glass thermometers are the cheapest kind of thermometer and are also easy to use. As you know metals are good conductors of heat.

Mercury is an ideal thermometer filling for 5 reasons. That is why mercury is used in thermometers. Why is Mercury Used in Thermometers.

Thermometers are a useful thing to have in your home. This means a column of mercury will expand and rise more than a column of alcohol for the same temperature change. There is a technical reason for using mercury in clinical thermometers.

Why is mercury used for pressure. It consists of a long glass tube which is graduated. Mercury has a greater coefficient of thermal expansion than alcohol.

Mercury has a lower coefficient of expansion compared with alcohol. Mercury fever thermometers are made of glass the size of a straw with a silvery-white liquid inside. Few materials can be liquid in a similar rangeand mercury is the only pure metal that is liquid at room temperature.

This means a column of mercury will expand and rise more than a column of alcohol for the same temperature change. Thermometers are a useful thing to have in your home. Mercury is the only one in liquid state at room temperature.

Mercury is the only metal that is in liquid state at room temperature. It doesnt wet the glass so you dont get i. Mercury has a high boiling point it may be used to detect greater temperatures as well.

Mercury is the only one in a liquid state at room temperature. Answer 1 of 2. Mercury has a boiling point which makes it suitable to measure higher temperatures.

Also it does not stick to any surface. Ad Wholesale China Products. Answer 1 of 75.

Why is mercury used in thermometers instead of alcohol. Why Mercury is a Great Thermometer Filling. A thermometric liquid is present within the tube which expands proportionally to temperaturehence measures it.

Even there is the slightest variation in temperature is noted by mercury so shows an immediate change. It is very reflective so its easy to see and to read accurately. Mercury has a lower coefficient of expansion compared with alcohol.

Why generally HgMercury is used in Thermometer. Mercury is used in thermometers because it is a metal that stays liquid in the room. They are common in many households schools and medical facilities.

There are two general types of mercury thermometers that measure body temperature. Its used in thermometers because it has high coefficient of expansion. But it has been used for a long time because it has certain properties that make it good for that application.

This continues until they are warm. Actually we try to avoid it these days. It expands uniformly when heated.

You can use one to detect a fever and people also often use them in cooking in order to determine if a roast is cooked to the proper temperature. You can use a thermometer to check if sugar is being melted or burned and if. When two bodies touch their temperature adjusts which means that the colder gets warmer the warmer gets colder.

It will not enlarge when it solidifies therefore it doesnt fracture the glass tube of the. Many of the other benefits I list would apply to most metals but being a solid. Mercury is easily the best liquid to use for 5 important reasons.

1 Having a very low melting temperature. It also has a high boiling point which makes it very suitable to measure higher temperatures. Mercury is in liquid state at room temperature.

All these reasons make it ideal for detecting high temperatures. Mercury is a liquid from -39 ºC to 357 ºC. It is used in thermometers because it has a high coefficient of expansion which makes it easy to move in the thermometers as per the temperatures.

Mercury is a good conductor of heat. One of them is fixed. It is used in thermometers because it has a high coefficient of expansion making it easier to move around in it when the temperature changes.

You can use a thermometer to check if sugar is being melted or burned and if. As a result you can get finer. Also it has the property of a high coefficient of expansion.

A clinical thermometer is used to measure human body temperature. As a result you can get finer. It has low specific heat.

Mercury has a greater coefficient of thermal expansion than alcohol. The other wire is can move along a threaded rod. Imagine two thin wires inside the capillary of your thermometer.

Gaurav Jhaa discussing here in detail about the rate of flow of mercury in cap. Mercury is commonly used in barometers because its high density means the height of. Its stage indicates the temperature as rapidly as potential and perfectly.

It is used in thermometers because it has a high coefficient of expansion. Mercury as a metal has a high electrical conductivity. Furthermore mercury has a low specific heat capacity and is a good conductor of heat.

Mercury is used in thermometers because it expands uniformly has a high boiling point and is available in a liquid state at room temperature. Mercury is best suited as a thermometric liquid. Mercury used in thermometers.

Why do we use mercury thermometer.
