Is it easier to determine accuracy or precision?
It is easier to determine precision because all you need are your measurements or data and no knowledge of whether your data are a true representation of whatever phenomenon you are studying. For example, suppose you wish to measure the boiling point of a liquid, so you heat the liquid slowly and record at what temperature the liquid begins boiling. You do this several times and record boiling points of 76.5, 76.2, 76.3 and 76.3 degrees. The data seem very precise meaning the values are close together and reproducible. If your thermometer is off by 5 degrees, however, your data are completely inaccurate, but you would have no way of knowing this. To determine the accuracy of your data you would need to measure the boiling point by several different methods, for example using an electronic thermometer or simultaneously heating with the same heating apparatus a substance with a known boiling point for comparison.
What is the boiling and freezing point of lead?

What state of matter is present at 30 degrees C?
boiling point.
Zero Celsius is the coldest temperature?
No zero celsius is the freezing point of water as 100 degrees is its boiling point
Which thermometer is most suitable for measuring boiling point of water mercury or alcholic thermometer?
Which thermometer is most suitable for measuring boiling point of water mercury or alcoholic thermometer
What is the most suitable thermometer for measuring boiling point of water?
- a thermometer with mercury - a thermometer with thermoresistance
Why can't and alcohol thermometer be used to measure the boiling point of water?
Because the boiling point of alcohol is lower than the boiling point of water.
What instrument measures boiling point?
You need a thermometer.
Why is the thermometer not suitable to measure the freezing point and boiling point of water?
Although a thermometer CAN be used its presence affects the temperature.
What effect does the use of an uncalibrated thermometer have on the boiling point of a liquid?
The thermometer's reading of the point the liquid boils may not be accurate.
How do you use boiling point in a sentence?
The boiling point is the temperature at which a substance boils. Different substances have different boiling points. The boiling point of water is 100 degrees Celsius. You have to have an accurate thermometer to measure boiling point.
What is the boiling point of the Celsius thermometer?
it is 212 degrees celsius
Why are the temperatures of the melting point of ice boiling point of water called fixed point in calibrating the thermometer?
it is because they were consistent at melting and boiling point
What is the boiling point of the thermometer?
The question to ask is: What is the boiling point of mercury (as mercury is the substance within a thermometer, unless of course you are referring to the material that makes up the thermometer itself).You can simply google that.But...it's 356.7° C
On a Fahrenheit thermometer the boiling point of water at sea level is?
212ºF
What is the use of thermometer in distillation?
1. The thermometer in the still head measures the boiling point of the liquid in the distillate. We can be sure of this because the boiling point of the boiling flask will vary based on how many compounds are in it. The thermometer measures the temperature of the vapor at the top of the column; this vapor will be cooled through the condenser and will condensate in the graduated cylinder at the product end of the apparatus. Therefore we are measuring the boiling point of the distillate vapor that is being condensed and collected.
