Why is mercury used in thermometers? Quora

Liquid in glass thermometers are the cheapest kind of thermometer, and are also easy to use. Mercury is easily the best liquid to use, for 5 important reasons. 1. It is very reflective, so it's easy to see and to read accurately. 2. It doesn't wet

Just how dangerous is mercury, anyway? ScienceIn

People tend to associate mercury with its silvery liquid form perhaps found in old thermometers. It was also used in electrical switches or relays that were built into machines until the mid

Mercury Thermometers Mercury US EPA

In a mercury thermometer, a glass tube is filled with mercury and a standard temperature scale is marked on the tube. With changes in temperature, the mercury expands and contracts, and the temperature can be read from the scale. Mercury thermometers can be used to

Why is mercury in a thermometer red? Ansaroo

Sourcequora. 0 0. Alcohol thermometers are considered much safer than the once popular mercury thermometers, but they are considered slightly less durable because the alcohol evaporates from the thermometer over time. The mercury in mercury thermometers is poisonous if the thermometer breaks.

Why Is the Metal Mercury a Liquid? ThoughtCo

Mercury is the only metal that is a liquid at normal temperatures and pressure. Why is mercury a liquid? What makes this element so special? Basically, it's because mercury is bad at sharingelectrons, that is. Most metal atoms readily share valence electrons with other atoms. The electrons in a mercury atom are bound more tightly than usual

The Best & Most Accurate Thermometers For Babies

2020 5 22 · Rectal thermometers are the most accurate. If suitable, you should try to use either of these methods, especially for younger children. When a baby is an infant, having a temperature reading thats even a few degrees off might make the difference of needing a trip to the hospital or not. Oral thermometers are also accurate. However, using an

How do barometers work? Explain that Stuff

The simplest kind of barometer is a tall closed tube standing upside down in a bath of mercury (a dense liquid metal at room temperature) so the liquid rises partly up the tube a bit like it does in a thermometer. We use mercury in barometers because it's more convenient than using water. Water is less dense (less heavy, in effect) than mercury

What Color is Mercury? Universe Today

Unlike all of the other planets in the Solar System, Mercury is just bare rock. It does have a tenuous atmosphere, but ground and space based observations see just the gray rocky color of Mercury.

Collecting Weather Data Physical Geography

Collecting Weather Data. Thermometers. Thermometers measure temperature. In an old style mercury thermometer, mercury is placed in a long, very narrow tube with a bulb. Because mercury is temperature sensitive, it expands when temperatures are high and contracts when they are low. A scale on the outside of the thermometer matches up with

What Is a Laboratory Thermometer? Reference

A laboratory thermometer is a tool used in laboratories to measure temperature with a high level of accuracy. It can be partially or fully immersed in the substance being measured. A laboratory thermometer is recognizable by its long stem with a silver bulb at the end. The silver color on the laboratory thermometer at the bulb normally

Hygrometer a Weather Instrument that Measure

Humidity is the amount of water vapor in the atmosphere caused by condensation and evaporation. It can be measured as absolute humidity (the amount of water vapor in a unit volume of air), or a relative humidity (the ratio of moisture in the atmosphere to the maximum moisture the atmosphere can hold). It is what gives you that uncomfortable sticky feeling on a hot day and can cause heat stroke.

Laboratory Thermometers Selection Guide

2020 5 19 · Laboratory thermometers are used to measure temperatures or temperature changes with a high degree of precision. They are made of metal or glass and strengthened through thermal tempering or annealing. The way a laboratory thermometer works depends upon
