No, melting always is physical.
As to the previous answer: reacting gold with an acid is not melting but oxidation.
Melting gold and pouring it into a mold is a physical change, not a chemical change. The gold's chemical composition remains the same throughout the process.
Melting a sample of gold is an example of a physical change.
No, unless it reacted with a gas in the air around it. Melting is a physical change.
Melting butter in a pan is a physical change. It involves a change in state from solid to liquid without altering the chemical composition of the butter.
Shortening melting is a physical change, not a chemical change or chemical property. When shortening melts, it undergoes a change in state from solid to liquid without any change in its chemical composition.
Melting gold and pouring it into a mold is a physical change, not a chemical change. The gold's chemical composition remains the same throughout the process.
Melting a sample of gold is an example of a physical change.
Melting is a physical process.
Melting of gold for jewellery making is a physical change as no new substance is formed after melting. Changes in state or phase are physical changes.
Physical.
No, unless it reacted with a gas in the air around it. Melting is a physical change.
No it's not because all you are doing is melting the gold, putting in into a mold and letting it harden. It would be a chemical change if you added some other substance to it during the progress.
no- melting is not a chemical change. It is merely a change in state of the same substance not a chemical reaction.
Melting is a physical change.
Melting is a physical change.
Melting snowflakes is a physical change, not a chemical change. The water molecules in the snowflake remain the same chemical composition before and after melting, they just change from a solid to a liquid state.
physical change according to physics nd chemical change according to chemistry
