Suppose you were measuring out an organic liquid, and some of it is evaporated after you have performed the volumetric measurement while you are weighing out the sample. What effect would this have on the densities you calculated? Will you overestimate or underestimate the density of the liquid? Would this cause poor accuracy, low precision, or both? Explain briefly.

Matter and Measurement

In the universe, there is matter, energy, and void space. The universe contains energy and void space. The definition of matter can be considered as something which possesses mass and consumes space. Chemistry is that branch of science which deals with the study of matter. Under chemistry, nature, composition, and the changes occurring to matter are discussed.
