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 %).
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.
What is the relationship between silicon content and the viscosity of magma?
Higher silicon content in magma leads to higher viscosity. This is because silicon tetrahedra form polymerized chains that hinder flow, making the magma more viscous. Lower silica content results in lower viscosity magma.
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.
What effects does water have on the viscosity of magma?
Adding water to a magma will decrease the viscosity of the melt. This happens because bonds within the silicon tetrahedron begin to break. When this breaking occurs it weakens the overall structure of the melt and doesn't allow the silica to accept other elements in order to form a complete bond.

What is the difference between viscosity and viscosity index?
Viscosity is resistance to flow of oil Viscosity Index is a scale to measure viscosity
Does soda have a low viscosity?
The viscosity is similar to the viscosity of water.
