In the video I found out that the solution is useless unless separated by distillation. The temperature relatively low, 40°C begins the process of fractional distillation. The most interesting piece of information I saw was that the higher the molecules the higher the boiling point. I guess this is from the fact that the solution is more dense, thus the boiling point needs to be higher to get the molecules to start to move faster. Sarita Ricchiuto

Sarita, OK. Your partly right about the boiling points. 5 stars. MW

I knew that some motion detectors required the infrared light given off by our bodies to lite. I also knew that our eyes are a form of photo sensors for visible light. I knew when light shines on any surface, the electrons can get ejected. I had no idea that motion sensors relied on the ability of light to initiate an electrical current. I also found it interesting that light can behave as a particle in some cases not just a wave. Lastly I learned that low frequency lights cause no electrons to ejects whereas, high frequencies send electrons flying out of light! Sincerely, Sarita Ricchiuto

Sarita, OK. Looks good! 5 stars. MW
