Do glass thermometers contain mercury?

The oldest thermometers used are mercury in glass. Newer thermometers include non-mercury liquids in glass and digital and electronic devices that use sensors to measure temperature. Thermometers that check body temperature in the ear, across the forehead, or have a digital display do not contain mercury.

Can you handle mercury with bare hands?

The chemical element mercury (Hg) is sometimes called quicksilver because of its liquid metallic appearance. While the sight of metal pouring from the hand is intriguing, mercury is extremely toxic when inhaled or touched and should never be handled with bare skin.

Does mercury vapor go away?

Liquid mercury vaporizes (evaporates) at room temperature causing elevated levels of mercury in indoor air. Mercury vapor is not irritating and has no odor, so people do not know when they are breathing it.

    The mercury-in-glass or mercury thermometer was invented by physicist Daniel Gabriel Fahrenheit in Amsterdam. It consists of a bulb containing mercury attached to a glass tube of narrow diameter; the volume of mercury in the tube is much less than the volume in the bulb. The volume of mercury changes slightly with temperature; the small change in volume drives the narrow mercury column a relatively long way up the tube. The space above the mercury may be filled with nitrogen gas or it may be at
