What are three uses for microscopes?
Three uses for microscopes are forensics, reasearch, and analysis.
How does a thermomerator measure temperature?
that depends on what type of thermometer. The tube thermometer, the kind with a glass tube with a red liquid in it, uses a small amount of mercury in a very small tube. When the mercury is heated, it expands, pushing further up the tube, as it cools it contracts, going down the tube. A dial thermometer also works on expansion and contraction, but with a coil instead of mercury.
What Type of thermometer uses mercury therefore considered unsafe to use?
The type of thermometer that uses mercury is called a mercury thermometer. These thermometers are considered unsafe because mercury is a toxic substance that can pose health risks if the thermometer breaks and spills. Due to these safety concerns, many countries have phased out or banned the use of mercury thermometers in favor of safer alternatives like digital or alcohol-based thermometers.
What are three uses for oxygen?
breathing burning
What are the uses of convection?
It means the transfer of thermal energy by the circulation movement of a liquid or gas.
What is three uses for mercury?
Please refer to the related links for an article about the uses for mercury.
What are three different sorts of thermomenters?
Mercury thermometer: uses the expansion of mercury to measure temperature. Digital thermometer: uses electronic sensors to quickly and accurately measure temperature. Infrared thermometer: measures temperature by detecting the infrared energy emitted by an object.
What are the uses and properties of Mercury?
There are no uses for mercury.
Describe how a thermometer uses the thermal expansion of a material to measure temperature?
A thermometer is a device that is used to gauge temperature. Mercury style thermometers used the elemental liquid in a tube of measured diameter and height. The higher the temperature, the higher the observed mercury level is. Thus, the height of the mercury uses marking to indicate which air temperature corresponds to the given height of its liquid expansion.
What chemical element has the symbol Hg?
Mercury has the chemical symbol Hg. It is a transition metal that is commonly known for its unique physical properties, such as being a liquid at room temperature. Mercury has a variety of uses, including in thermometers, barometers, and fluorescent lights.
What are the important uses of Mercury?
mercury is used in thermometers
What are the differences between mercury and salt in terms of their properties and uses?
Mercury is a liquid metal at room temperature, while salt is a solid compound. Mercury is toxic and conducts electricity, while salt is non-toxic and does not conduct electricity. Mercury is used in thermometers and barometers, while salt is commonly used as a seasoning and preservative in food.
Can Hg turn into liquid at room temperature?
Hg (mercury) IS a liquid at room temperature. [and Mark adds...] Unless this is some kind of trick question, Hg, or Mercury, is a liquid at room temperature. Until it was labeled as "bad", mercury was used in oral and rectal thermometers, and it is still seen in positional or gravity-driven switches. Mercury is found in some older home furnace thermostats. When connected to a spring that coils and uncoils as the temperature changes, the mercury, "floats" in a sealed glass tube that has two wires at one end. The switch, riding on the coil, will make contact as it tilts to activate the furnace. Mercury can be ionized into a gas and used for propulsion in space. I don't know of any uses for solid/frozen mercury.
What are Mercury's uses as an element compound?
you will allways see mercury in conventional thermometers.
What are the uses of a Mercury barometer?
A Mercury barometer is used to measure atmospheric pressure.
What instrument uses Mercury?
Historical, both thermometers and barometers have used mercury.
How does a thermometer use the thermal expansion of a material to measure temperature?
A thermometer uses a liquid, such as mercury or alcohol, that expands and contracts with temperature changes. As the temperature increases, the liquid expands, causing it to rise up a calibrated tube. The level of the liquid in the tube corresponds to the temperature reading indicated on the scale.
