Characteristics of Critical Thinking Critical thinking involves the use of a kind of thinking called reasoning, in which we construct and/or evaluate reasons to support beliefs. Critical thinking also involves reflection the examination and evaluation of our own and others thoughts and ideas. Finally critical thinking is practical.
If you measure liquid temperature while distilling, you may have noticed that liquid temp can often be much higher than 174 before a still starts producing. Again, the boiling temperature of a solution that is 100% ethanol is 174 degrees.
The distillation flask is a round-bottom flask. The liquid to be distilled should fill the distillation. flask to ~50-60% of its capacity. To promote even heating of the liquid, a boiling chip or a. magnetic stir bar is added before heat is applied to the distillation flask. The irregular chips. provide sites for bubbles of vapor to form, or alternatively the liquid is agitated with the magnetic. stirrer as it is being heated. Never add a boiling chip or a stir bar to a hot liquid! Doing so can. cause a seemingly calm liquid to boil suddenly and violently.
