Is pouring molten gold into a mold a physical change?
Yes. Gold would have to bond with something for it to be a chemical change.
Is pouring molten silver into a mould to solidify and make jewellery a physical change?
Yes, pouring molten silver into a mold to make jewelry is a physical change. This process involves a change in the state of matter from liquid to solid without altering the chemical composition of the silver.
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.
Is melting a sugar cube a chemical change?
Burning or oxidization is always a chemical change. The process takes in Oxygen and Sugar and outputs different compounds including water, carbon dioxide, carbon monoxide, and other carbon residue.
Is turning a penny gold a chemical or physical reaction?
Turning a penny gold is a physical reaction rather than a chemical reaction. This process involves coating the penny with a layer of gold, which changes its appearance but does not alter the chemical composition of the penny itself.
Is pouring molten gold into a mold a physical change?
Yes. Gold would have to bond with something for it to be a chemical change.
Is pouring molten silver into a mould to solidify and make jewellery a physical change?
Yes, pouring molten silver into a mold to make jewelry is a physical change. This process involves a change in the state of matter from liquid to solid without altering the chemical composition of the silver.
Is making molten glass a physical or chemical change?
Melting is a physical process.
When molten rock cools and hardens is a physical change or chemical change?
When molten rock cools and hardens, it is a physical change because the composition of the rock remains the same. The change in state from liquid to solid does not alter the chemical makeup of the rock.
Is using oxygen to separate molten copper sulfide into copper sulfur dioxide a physical change?
no it is a chemical change
Is iron melting a physical change?
Melting iron is a strictly physical change (change of state). The molten and solid iron would be identical by any chemical test or reaction.
Is heating sodium chloride a chemical change?
No, heating sodium chloride is a physical change rather than a chemical change. When heated, sodium chloride simply changes physical state from a solid to a liquid (molten form) without any change in its chemical composition.
Is Using oxygen to separate molten copper sulfide into copper and sulfur dioxide a physical change?
No, using oxygen to separate molten copper sulfide into copper and sulfur dioxide is a chemical change because new substances with different chemical properties are formed. This process involves a chemical reaction where the copper sulfide is broken down into copper and sulfur dioxide molecules.
Is the melting point of silver a physical or a chemical property?
The change in the state of matter between solid, liquid and gas are not chemical changes. The melting point of a substance, silver in this case, is a physical characteristic.
Is molten lava hardening into a rock a physical change?
It's a physical change - more intermolecular bonds (bonds between different molecules) are formed due to the cooling of the matter, and the state of matter changes from liquid to solid. The chemical makeup of the lava does not change.
Is sodium and potassium reacting violently with water a chemical or physical change?
Their reaction with the water is a purely chemical change, however the chemical reaction is so intense and violent that it is usually followed by many dangerous physical changes (e.g. boiling of the water, flinging molten pieces of the unreacted metal at you, spattering drops of lye solution at you).
Is a glass blower creating sculptures a physical or chemical change?
