Classify each of the following by the type of solid (molecular, ionic, metallic, covalent network) it will form: a. Na b. Fe c. SiO2 d. H2O e. KF A covalent bond is the result of: a. t...
Crystals are solid materials with a natural geometrically regular form, while quartz is a specific type of crystal made of silicon dioxide.
There are three main types of rock — igneous, sedimentary and metamorphic — with varying mineral mixes depending on where and how the rock came to be. Igneous rocks — which form as magma solidifies either deep within Earth or at the surface after a volcanic eruption, for example — c...
Vacuum tubes are still used in many microwave ovens, but that’s in addition to solid-state semiconductor technology. Here are some of the most common uses of semiconductors made from crystalline silicon wafers: Solar panels and other photovoltaic modules ...

The ball is commonly known as a free air ball (FAB) and after melting it rapidly solidifies and the FAB consists of several large grains. During ball formation heat also travels along the length of the wire and the grain size varies gradually from the very large grains in the FAB to ...
If electric cars are the future, will they also be the thing that finally makes solar take off? Or will there be some other catalyst? The economics of solar has always been challenging. Ten year paybacks are not the path to rapid adoption. I believe that the cost of solar has come dow...
