Is making glass from sand a chemical change?
The Journey into the hole
Is a glassblower creating sculpture out of glass a physical change or a chemical change?
A physical change; you're turning the solid glass into a semi-liquid molten state, forming it into a desired shape, and then allowing it to cool and harden.
How would the heating curve for glass be different from the heating curve for water?
The heating curve for glass would show a gradual and steady increase in temperature until it reaches its softening point, where it begins to deform. In contrast, the heating curve for water would show a relatively stable temperature increase until it reaches its boiling point, at which point the temperature remains constant until all the water has evaporated.
Is breaking of glass physical or chemical change?
It is a physical change. The resulting fragments of glass are still glass and of the same composition.
Is glass breaking a chemical or physical change and why?
Glass breaking is a physical change because it does not involve a change in the chemical makeup of the glass. The bonds between the glass molecules are simply being rearranged when it breaks, but the composition of the glass remains the same.
Is heating a glass a chemical or physical change?
Heating is a physical process.
Is heating a glass tubing a physical or chemical change?
Heating is a physical process.
Is a glass blower creating sculptures a physical or chemical change?
yes it is a chemical change because it turned into something new a scultureWRITTEN BY ISABELLA GARCIAIN ROGERS MIDDLE SCHOOL6TH GRADE
Is breaking glass chemical or physical?
Breaking glass is a physical change, as it does not change the chemical composition of the material.
Is a glass breaking a chemical change?
A chemical change is when the molecules of an object / solution are changed. A physical change is when the object / solution is altered without molecular change. Breaking glass is a physical change.
Is making glass from sand a chemical change?

Is breaking glass a physical change?
Yes, as it's still glass. There is no chemical/molecular change.
Is a glassblower creating sculpture out of glass a physical change or a chemical change?
A physical change; you're turning the solid glass into a semi-liquid molten state, forming it into a desired shape, and then allowing it to cool and harden.
When glass brakes is it a physical change?
A glass breaking is a physical change because the chemical composition of the glass does not change.
Is mixing of glass pieces and sand a chemical change or physical change?
it is a chemical change.
Is hot glass cracking when placed into cold water a chemical or physical change?
It is a physical change because the chemical composition of the glass does not change.
