Which the following should be used to measure the temperature of liquid?
A thermometer should be used to measure the temperature of liquid. Digital thermometers are more accurate and quicker to read than traditional mercury thermometers. Make sure to choose a thermometer that is suitable for measuring liquid temperatures specifically.
What is used in thermometers now instead of mercury?
Many modern thermometers use a colored alcohol solution, typically dyed red or blue, instead of mercury. These alcohol solutions have lower toxicity levels than mercury and are safer to use in household and medical applications. Other alternatives include digital thermometers that use thermistors or infrared technology to measure temperature.
Why Mercury thermometer is used domestically and alcoholic thermometer in lab?
Mercury thermometers are used domestically because they are reliable, have a wide temperature range, and are easy to read. Alcoholic thermometers are used in labs because they are non-toxic and can measure a wide range of temperatures accurately. Additionally, they have a lower risk of shattering compared to mercury thermometers.
How accurate is a thermometer?
A thermometer can be accurate if used correctly and calibrated regularly. However, factors such as environmental conditions and handling can affect its accuracy. Digital thermometers tend to be more accurate than traditional mercury thermometers.
How inaccurate is underarm thermometer?
Underarm thermometers can be less accurate than other types of thermometers, such as oral or rectal thermometers. They can be affected by factors like ambient temperature, sweating, and clothing. For the most accurate reading, it's best to use a thermometer in the mouth, rectum, or ear.
Why can't and alcohol thermometer be used to measure the boiling point of water?
Alcohol thermometers typically have a lower maximum temperature range compared to mercury thermometers, making them unsuitable for measuring the high boiling point of water. Alcohol thermometers may not accurately measure temperatures above their boiling point, which is lower than water's boiling point.
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.
Whether the body temperature can be measured by keeping the thermometer at some place other than mouth?
Yes, you can measure body temperature by putting the thermometer under your arm (in which case it should measure below 36.5 degrees Celsius.) You can also get ear thermometers, but these work quite differently to regular oral/underarm thermometers. Forehead thermometers are also available.
Why do you use rubbing alcohol in thermometer?
Rubbing alcohol is used in thermometers because it has a lower freezing point than water, allowing the thermometer to measure lower temperatures accurately. Additionally, alcohol has a wider temperature range than mercury, making it suitable for various types of thermometers.
What is the difference between alcohol thermometers and digital thermometers?
Alcohol thermometers use a liquid such as ethanol to measure temperature based on the expansion of the liquid, while digital thermometers use electronic sensors to detect temperature changes and provide a numerical reading. Digital thermometers tend to be more accurate and easier to read than alcohol thermometers.

What are the materials for does hot water freeze faster than cold water?
The materials needed for the experiment are: two containers to hold the water, hot water, cold water, thermometers to measure the temperature, a freezer to freeze the water, and a timer to record the time it takes for each to freeze.
Why Mercury thermometer is used domestically and alcoholic thermometer in lab?

Alcoholic thermometers are used in labs because they are non-toxic and can measure a wide range of temperatures accurately. Additionally, they have a lower risk of shattering compared to mercury thermometers.
Why does a wet bulb thermometer measure lower than a dry bulb thermometer?
It happens due to: 1)Insufficient evaporation taking place from the wet bulb due to salt and dust or other impurities on the muslin,or due to presence of no water on the muslin. 2)It maybe due to difference in sensitivities of both the thermometers whereby one of them is slow in recording sudden changes of temperatures. 3)Lastly,maybe due to faculty of broken thermometers.
What materials do you need to do does salt water boil faster than plain water?
To test whether salt water boils faster than plain water, you'll need a stove, two identical pots, water, salt, thermometers, and a timer. Fill one pot with plain water and the other with salt water (salt dissolved in water). Heat both pots at the same time, measure the time it takes for each to reach boiling point, and record the results.
A liquid that is more dense than water is?
shampoo is denser than water or mix cornstarch and water and that is denser than water too.
