Principles of Distillation

What is distillation? Simply, distillation is the process in which a liquid is vaporized (turned to steam), recondensed (turned back into a liquid) and collected in a container. Nature uses a form of distillation to turn salt water (seawater) into fresh water (rain). Why do you use distillation to recycle waste solvents? Solvent-based waste contains… View Article

Balloons Paper

Why does a hot air balloon float even though it is so heavy? Hot air balloons float because the buoyancy force of the hot air is more than the weight. Buoyancy occurs because the hot air has a lower density than the cooler outside air. This lower density air weighs less than the air it… View Article
