Charcoal one of the earliest known forms of ink, was used as early as 30,000 BC. The first of its use documented in the continent of Europe. It may be a bit primitive to these modern times but still very useable for those who want to try it. The recipe of making it however is similar to those inks made by ancient civilizations such as the ink used by the Ancient Egyptians. We propose to make charcoal ink as a…

Biology Lab for Virtual School.. Lesson 1.04

When an object falls onto the surface, it has to push the water molecules apart. If the effect of the weight of the object is insufficient to match the attractive forces between molecules in the surface layer, the object will not enter the surface. Molecules of most detergents and soaps are long chain hydrocarbon molecules with an ionic group at one end, usually carrying a negative charge, thus making it an anion. www.sciencedaily.com/articles/s/soap_bubles.html When the drop of detergent is added…

Signficance of the Study

Our study, which is how to make an effective Floorwax without using gas . Instead We used cooking oil (used). It has a lot of significance on life of everyone. The first one is that it helps us avoid Respiratory Diseases, how? For example You’ll use a Floorwax cleaning the floor because of the gas contained on it you may take the gas emitted by the Floorwax and it may affect your Respiratory System. Another importance of our study is…

Determining the Melting Point of a Substance

Questions: 1. The effect of the impurity on the mixture caused the melting point of the mixture to be lowered. 2. The reason why the melting point of a binary mixture is lowered, is due to the fact that the mixture of the two components has caused the structure of the solid to change and become less organized (not as strong). Therefore causing the mixture to melt at a lower temperature. The melting point is broadened because the mixture has…
