That is a easy question. Basically what you need to find out is whether you like silica sand or to use glass changes on a molecular level when heated (chemical change), or is just melted into another form (physical change).
However, after some research, it appears that to make glass, you simply melt silica sand (or some other form of silica) into the resulting product... Glass! There is no chemical reaction or molecular change.
The ConclusionTherefore, making glass from sand is a physical, not a chemical, change.
What else can I help you with?
Is separate sand from grave a physical or chemical change?
Physical because you are not changing the substance.
What is the main ingredient used in making glass?
The main ingredient used in making glass is silica sand, which is a form of silicon dioxide. Other ingredients like soda ash and limestone are often added to the silica sand to lower the melting point and improve the glass properties.
Is sand flowing through an hour glass an chemical or physical change?
It is not really a change, at all. Sand is moving from one spot to another. If it truly had to be categorized, I would put it under a physical change. A physical change would be a change in an object you can see with your eyes. However, the chemical makeup of that object does not change. In other words, no new chemical is formed. For example, water may freeze or evaporate, but the chemical makeup of water, no matter what state it is in, is H2O. A chemical change would would result in the formation of one or more new chemicals. For example, burning paper is a chemical change. You have paper and fire, and when you burn the paper up, it gives off CO2, and charred paper, which is different from regular paper.
Is Sand being washed out to sea from the beach is a chemical change?
no, its physical change :)
Is glass made partly of sand?
Yes, glass is made from a combination of sand, soda ash, and limestone. These raw materials are melted together at high temperatures to form glass. Sand is the major component, making up around 70-75% of the composition of most types of glass.
What evidence do you have that changing sand into glass is a chemical change?
Making glass from sand is a physical because the actual composition of the substance (silica) is not changing. Making glass is just melting all the bits of sand into a large piece (glass).
Is mixing of glass pieces and sand a chemical change or physical change?
it is a chemical change.
What evidence do we have that changing sand to glass is a chemical change?
Glass contain not only melted sand but also other compounds forming new compounds.
Is glass a chemical or physical change?
The transformation of sand, soda ash, and limestone into glass is a chemical change because it involves the formation of new chemical bonds. However, shaping or molding the glass through processes like blowing or cutting is a physical change since the chemical composition of the glass remains unchanged.
Why do sand and glass have the same chemical symbol?
Sand is primarily made up of silicon dioxide, which has the chemical formula SiO2. Glass is made by melting sand, so it also contains silicon dioxide at its core, hence the same chemical symbol for both.
What is glass making?
silicon (aka sand)
Is dirt in the making of glass?
no, sand is heated to make glass :) youtwat.^.^
Can there be a chemical change in sand?
no.
Why is separating sand from gravel a chemical change?
No it is not a Chemical Change. It is a Physical Change.
What is the main substance used making glass?
This is the same sand as common beach sand.
Is sand and water mixed a chemical and physical change?
Chemical
Why can't sand be used for making pots?
It can be, its called glass.
