What is the relationship in the silicon content and the viscosity of magma?
There is an inverse relationship between magma viscosity and silicon content. Lavas erupting from basaltic volcanoes (like Hawaii) have a much lower viscosity and are much hotter than those erupted by volcanoes whose magmas are rich in silicon. There may be up to 8 orders of magnitude viscosity difference between basaltic magmas (SiO2 contents or about 45 %) and rhyolitic magmas (SiO2 > 70 %).
What element has the greatest effect on magma characteristics?
The silica content in magma has the greatest effect on its characteristics. High silica content makes magma more viscous and results in explosive volcanic eruptions, while low silica content produces runny magma and less explosive eruptions.
What is fluid lava?
Fluid lava refers to lava that has a low viscosity, meaning it flows easily. This type of lava is typically found in shield volcanoes and can travel long distances from the volcanic vent before cooling and solidifying. Fluid lava eruptions are typically less explosive compared to those with more viscous lava.
Is the silica content in igneous rock of low viscosity?
Different igneous rocks have different silica contents. I could go into loads of detail about mineralogy but what you probably need to know is that magma (as rock is immeasurably viscous as it is solid) containing high Si is more viscous that that with low Si (Silicon being Si). Basalt has low Si, andesite has high Si. Both are extrusive igneous, but form at different plate boundary types.
Does rhyolite have silicon in it?
Yes, rhyolite contains a significant amount of silicon dioxide (SiO2), which is the main component responsible for its high silica content. Silicon is present in the form of silicon dioxide in rhyolite.

What is the viscosity of silicon?
i think its i DONT Know
Why are silicon are better lubricants than petroleum products?
because they have better thermal stability then petroleum as silicon viscosity dont change due to temperature change while petroleum viscosity changes with any change in its tempareture
What is the role of silicon in welding electrodes?
Silicon is used to lower the viscosity of the weld puddle. This allows better flow of the molten weld puddle.
Why rotating electrical machines have low silicon content?
Rotating electrical machines have low silicon content in their core material to reduce hysteresis losses and improve efficiency. Silicon content affects the magnetic properties of the core, and by controlling the silicon content, manufacturers can optimize the performance of the machine for its intended application. Additionally, low silicon content can help reduce manufacturing costs and make the machine more cost-effective.

Why sheet steel with high silicon content is used in transformer core whereas lower silicon content sheet for rotating machine?
high permeability ,low hysterisis,increased resistivity

Relationship between geology and computer?
Computers are made from geological materials, like silicon chips from silicate minerals, wiring from copper minerals, solders from tin and so on.
What is the distance between Si atoms in solid silicon?
2.22 angstroms is the distance between Si atoms in solid silicon.
