How do magnets under thermometers affect its ability to tell temperature?
If you are talking about a regular liquid filled thermometer (alcohol or mercury), they don't. Alcohol and mercury aren't magnetic. A lot of thermometers have magnets on the back so they can be attached to a refrigerator or metal beam. Maybe, if you had a really strong magnet, a mechanical thermometer (like a bi-metallic strip used in a thermostat) could be affected by a magnet, but I doubt it.
Why is an alcohol thermometer better than mercury in the freezer?
Dropped mercury thermometers account for almost half of the spills that occur each year on campus. Rarely do people have the mercury spill kit required to clean up the half a gram of mercury that can escape from these thermometers. If someone drops a mercury thermometer in your lab, you lose time, money, and possibly your clothing or equipment. Instead, recycle your mercury-filled thermometers through EH&S and we'll deliver a free alcohol-filled thermometer in exchange. Our alcohol thermometers are semi-submersible and measure from -20 to 110ºC to within 1º. They perform most routine laboratory functions that mercury thermometers are used for, such as measuring the temperature of water baths or ambient air. And best of all, when you drop one, all you have to do is wipe up the liquid with a paper towel and throw it away, and place the broken glass in your lab glass bin.

How floroscent tubelight works?
The glass tube is filled with mercury gas. Electricity causes the gas molecules to vibrate faster. The increased motion excites phosphorous in the tube and causes it to give off visible light.
Whould an aluminum ball sink or float?
Depends on the medium, and whether the ball is solid or not. A solid ball would float on mercury, sink in water. If it were hollow enough (or filled with, say, cork) it would float in water.
This instrument is often filled with mercury colored water or alcohol?
The instrument you are referring to is likely a thermometer. Thermometers are commonly filled with either colored alcohol or mercury to measure temperature changes based on the expansion or contraction of the liquid inside.
What are thermometers filled with besides mercury?
Thermometers can be filled with alcohol, which is a less toxic alternative to mercury. Some modern thermometers use digital sensors to measure temperature, eliminating the need for any liquid filling.
What instrument will you use to get the temperature of the water?
A thermometer is typically used to measure the temperature of water. There are different types of thermometers such as digital thermometers, and mercury or alcohol-filled thermometers, that can be used depending on the specific requirements of the situation.
Why is alcohol red in colour in thermometer when alcohol is a colourless liquid?
Traditional thermometers are filled with red-dyed alcohol while others are filled with mercury which appears silver in color. Mercury thermometers aren't safe. When a mercury thermometer breaks on the floor mercury is released. Mercury is very toxic and venomous. One sole drop can kill you or make you very sick. Alcohol is dyed red to add more visibility. Otherwise it'll be very hard to read the temperature due to the alcohol's transparency.
What is a barometer filled with?
A barometer is typically filled with either mercury or a special type of alcohol, such as ethanol or isopropanol. Mercury has traditionally been a common choice due to its density and stability for measuring atmospheric pressure.
What does the thermometer mean?
A thermometer is a tool used to measure temperature. It typically consists of a glass tube filled with mercury or colored alcohol that expands or contracts with temperature changes, allowing us to gauge how hot or cold a particular environment is.
What is the instrument used to determine air pressure is called?
The instrument used to determine air pressure is called a barometer. A simple barometer is a long glass tube filled with mercury that it turned upside down into another container filled with mercury.
Is there air inside a laboratory thermometer?
No, laboratory thermometers are typically filled with an inert gas like nitrogen or filled with a liquid such as mercury or alcohol. The absence of air prevents fluctuations due to temperature changes.
What modern meteorological instrument measures atmospheric pressure?
A barometer is the modern meteorological instrument that is used to measure atmospheric pressure. It typically consists of a sealed glass tube filled with mercury that reacts to changes in pressure. The level of mercury in the tube rises and falls depending on the atmospheric pressure.
What type of thermometer is widely used in science classrooms?
Frequently thermometers filled with an alcohol; but also thermometers with mercury, with thermoresistance, thermocouples, etc.
What instrument measures how hot or cold something is?
A thermometer is the instrument used to measure how hot or cold something is. It typically consists of a small tube filled with a liquid (such as mercury or alcohol) that expands or contracts based on the temperature, indicating a numerical value on a scale.
Why can't you use mercury thermometers?
Mercury is toxic and poses serious health and environmental risks if the thermometer were to break. Safer alternatives, such as digital thermometers or alcohol-filled thermometers, are now commonly used instead.
