What elements is a liquid metal used in thermometers?
Mercury is used in thermometers, barometers, manometers, float valves, mercury switches, and other devices. Concerns about the element’s toxicity have led to mercury thermometers being largely phased out in clinical environments in favor of alcohol-filled instruments.
Which metal is liquid at room temperature that is used in thermometers?
Mercury
Mercury is a silvery-white poisonous metallic element. Mercury is liquid at room temperature and used in thermometers, barometers, fluorescent lighting, batteries and in the preparation of chemical pesticides. Mercury is also sometimes called quicksilver or liquid silver. The chemical symbol for Mercury is Hg.
Which element is a liquid metal?
Mercury is the only elemental metal that is liquid at room temperature. (Cesium melts at about 28.5 °C [83 °F], gallium at about 30 °C [86 °F], and rubidium at about 39 °C [102 °F].)
What liquid is used in thermometers?
Mercury is one of the most familiar materials used in liquid thermometers. Other liquids, such as kerosene or ethanol, may also be used in these types of thermometers.
Which is the liquid non metal?
bromine
One non-metal, bromine, is a liquid at room temperature. The other non-metals are solids at room temperature, including carbon and sulfur.
What element fills balloons and stars?
After hydrogen, helium is the second most abundant element in the universe. It is present in all stars. It was, and is still being, formed from alpha-particle decay of radioactive elements in the Earth. Some of the helium formed escapes into the atmosphere, which contains about 5 parts per million by volume.
Which metal can be cut with knife?
Sodium
Sodium is silver white color metal with malleable and ductile property. It is the metal that can easily be cut with a knife.
Which is the liquid non-metal?
Which metal can easily cut with knife?

What liquid is in a Galileo thermometer?
Hello Caroline, The liquid in AcuRite Galileo Thermometers is 100% paraffin. The colored bulbs are filled with paraffin and 3.4% dye. The liquid is non-toxic.
Can you touch mercury?
Mercury is a very toxic or poisonous substance that people can be exposed to in several ways. If it is swallowed, like from a broken thermometer, it mostly passes through your body and very little is absorbed. If you touch it, a small amount may pass through your skin, but not usually enough to harm you.
