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.
Who is the divisor of centigrade thermomoter?
The divisor of a centigrade thermometer is the scale used to measure temperature, which is based on the Celsius scale. In this scale, the freezing point of water is marked as 0 degrees Celsius, while the boiling point is marked as 100 degrees Celsius at standard atmospheric pressure. The thermometer divides the temperature range between these two points into 100 equal intervals or degrees. Each degree represents a change in temperature of one centigrade unit.
What is the boiling and freezing point of lead?
The freezing and boiling points of lead are both 1740.0 degrees celsius.
What are 5 pysiacal properties?
mass, volume, density, melting point, boiling point
What state of matter is present at 30 degrees C?
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 instrument measures boiling point?
A thermometer is typically used to measure the boiling point of a substance. It can accurately measure the temperature at which a liquid changes state from a liquid to a gas during the boiling process.
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
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 is the boiling point of the Celsius thermometer?
it is 212 degrees celsius
What is the boiling point of water in degrees Celsius on a thermometer?
The boiling point of water is 100 degrees Celsius and the melting point of water is 0 degrees Celsius
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.
On a Fahrenheit thermometer the boiling point of water at sea level is?
212ºF
What is the upper fixed point in the thermometer?
The upper fixed point on a thermometer is the temperature set at 100 degrees Celsius, which corresponds to the boiling point of water at standard atmospheric pressure. This fixed point is used as a reference point for calibrating the thermometer.
What would the temperature reading be on the thermometer when ink has been boiling for two minutes?
The temperature would depend on the boiling point of the ink. The thermometer would likely show a temperature close to the boiling point of the ink, which could vary depending on the type of ink being boiled.
What effect does the use of an uncalibrated thermometer have on the boiling point of a liquid?
Using an uncalibrated thermometer can result in an incorrect measurement of the boiling point of a liquid. This can lead to inaccurate data for experiments or cooking processes. It is important to calibrate thermometers regularly to ensure accurate temperature readings.
What equipment is used to determine the boiling point of salt water and sugar water?
A boiling point apparatus or device, such as a distillation setup with a thermometer, can be used to determine the boiling point of salt water and sugar water. This setup typically includes a heat source, a round-bottom flask to hold the solution, a condenser to collect and condense the evaporated liquid, and a thermometer to monitor the temperature as the solution boils.
