Ho does a thermometer measure temperature?
A thermometer measures temperature by using the liquid inside of the thermometer. It measures temperature by Celsius and Fahrenheit.
What is the difference between accuracy and precision and which is most important to scientific measurement?
Both accuracy and precision are important to scientific measurement. I'll try to explain the difference with a couple of illustrations. I should start by saying, sometimes the words are used interchangeably but they shouldn't be. I consider precision to mean resolution. That is how fine/small a reading you can get.Assume an electronic thermometer (digital display) can display answers to the nearest one hundredth of a degree. But, the thermometer isn't able to measure with that accurately. Maybe it's only accurate to the nearest whole degree. In this case the precision is greater than is supported by the accuracy of the device.Now take the opposite case where the thermometer is able to measure temperature accurately to one hundredth of a degree but the instrument can only display whole degrees. In this case the precision does not support the accuracy.Ideally the accuracy and precision of an instrument are the same but often that's not the case.
How much temperature has to raise to get a reading?
It depends on the thermometer that you are using.
What would you measure using a thermometer?
You would measure temp.
How do you tell how hot or cold something is?
use a thermometer.We can feel how hot or cold something is. However, sometimes things are just too hot or cold for us to feel safely. At other times we need to know exactly how hot or cold something is. When we need to measure temperature correctly we need to use an instrument called a thermometer. This measures temperature in degrees Celsius [sometimes called centigrade] or degrees Fahrenheit. There are different types of thermometers for different situations. A medical thermometer, for example, needs to be very accurate. It measures in fractions of degrees. When we are ill, even tiny changes in temperature are important. Some thermometers use a liquid that moves up a very fine glass tube. Most room thermometers, and outdoor thermometers are like this. The liquid is either mercury [ which is poisonous] or coloured alcohol. As liquids get warmer they expand [get bigger], and move up the tube. Water expands too, but not as much as alcohol and mercury. Thermometers that might be used by small children are not made of glass. They use a digital display which lights up the temperature. Inside the displays are chemicals that change colour according to the temperature.
A thermometer measures temperature to the nearest 0.5 and degC. Which measurement shows an appropriate level of precision for the thermometer?
the answer is 16.0 °C
Desirable properities in a mercury thermometer?
The two properties you would want in a mercury thermometer are accuracy and precision. Accuracy is important because you want to know that it is recording the right temperature, and precision is important because it allows you to know the exact temperature to the extent of the gradations of that thermometer. Cherry flavor would be nice too! :)
What is the purpose of using thermometer?
A thermometer is for measuring temperature.
Can you give me a sentence using the word precision?

What is the raw experimental measurement made when using mercury thermometer?
Using a thermometer we can measure the temperature.
How global weather is monitored?
By using a thermometer and the barometer.=)
What are safety measures for handling thermometer?
safety measures in using a thermometer
What two items are in a thermometer?
A precision capillary tube with a graduated scale and a liquid such as mercury or alcohol that will expand as the temp increases.
What decimal position can you measure accurately using a thermometer?
using a thermometer u can measure accurately at 1 decimal place
Temperature is measured using a?
thermometer
How do you use the word thermometer in a sentence?
When I got sick, I had to take my temperature using a thermometer.
What are three ways of taking a vital temperature?
Three ways of taking a vital temperature are using a digital thermometer orally, using a tympanic thermometer in the ear, or using a temporal artery thermometer on the forehead.
