Sublimation

 process in which a solid passes DIRECTLY to the gaseous state and back to the solid state without being a liquid

Extraction

technique based on the solubility of the individual components of the mixture; removal of a component

Decantation

separate a liquid from a solid by carefully pouring off the liquid into a separate container

Filtration

material passes through a filter and allows the liquid to go through, keeping the solid/ other substance

Accuracy

how close your experimental value is to the actual value; measurements that is widely accepted

Experimental value

the data collected in the experiment

Precision

agreement among several measurements

Meniscus

curved surface of a liquid; read the results of liquid measurement from this point

Random Errors

• "built in" error and connot be corrected
• includes the uncertainty of the instruments

 Systematic errors

• experimental error
• if you were to repeat experiment, you could fix
• what you could do better

Actual value

measurement that is widely accepted or defined

Calibration

a process in which a scientist checks to see if a device is working properly and that it provides an accurate measurement

Interpolation

use of the calibration curve to show the accurate reading of the lab tool by predicting the outcome

Corrected Boiling Point

boiling point of liquid after calibrated
