∙ 11y agoThat's going to depend. If it's warmer than 5,909° F, it's a vapor. If it's not quite
that warm but still over 2,577° F, then it's liquid. If you're holding it in your hand,
chances are high that it's solid.

What is silicon Oxidation state?
Silicon's oxidation state (Si) is zero because it is in its elemental form.
What exists as covalent crystals in the solid state?
silicon
What properties of silicon dioxide make it sueful in sandpaper?
Use/equipment Your chemical dioxide Main properties to use Chemical or physical properties? Fire extinguisher Carbon dioxide - CO2 does not conduct electricity. - CO2 is heavy (dense) so it covers fire and removes the oxygen. - CO2 does not burn. Physical physical chemical Electrical wires Copper -copper can bend (malleable) -conducts electricity - does not corrode easily Physical Physical Chemical Welding Argon -very unreactive, so it provides an inert atmosphere. Chemical Sand paper Silicon dioxide It very hard and does not crumble (not brittle) -High melting point Physical Physical Tools Iron -Iron is strong and hard -Iron can change shape (malleable) Physical Physical Computer circuits Silicon -Silicon can conduct electricity. -silicon has very high melting points.

What state of matter is silicon dioxide?
It is sand so SOLID
Is there a difference between silica and silicon?
Yes. Silica is a compound with the formula SiO2, while silicon is an element with symbol Si. There are many chemical and physical differences between them.
What would the physical state be of silicon oxide be at 25 degrees?
solid
Is it a chemical or physical when silicon seed crystals grow into silicon ingots?
A physical phenomenon
Can silicon undergo a physical and chemical change?
Yes silicon can undergo physical and chemical changes.
What is the physicals state of silicon at room temperature?
The state of silicon at room temperature is SOLID State.
What is silicon Oxidation state?
Silicon's oxidation state (Si) is zero because it is in its elemental form.
What exists as covalent crystals in the solid state?
silicon
What is the malleability of silicon?
silicon can be malleable when mixed with other element like carbon, oxygen (etc...) on the other hand silicon can in a solid state when it is in its pure state.
