Not all liquids have the same boiling point. Sometimes, chemists are able to use those different volatility points in order to separate liquids during a process called distillation. You may have seen the process in action if you ever visited…
Experiment with writing down number measurements for several different categories so that the next time you are cooking, sewing, or measuring furniture, you will get the right measurement the first time. The most pronounced difference in measuring categories is between…
