Melting is a physical process.
Pouring molten gold in a mold is a physical change because it involves a change in state from liquid to solid without altering the chemical composition of the gold.
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.
Pouring milk into a glass is a physical change. This is because the milk remains the same substance (liquid milk) even after it is poured into the glass.
yes it is because a chemical change is way different than physical and a physical change is when it is still the same for example when you rip cut or crumble a pice of paper it is still the same !
Hardening of ketchup is typically a physical change, as it does not involve a change in the chemical composition of the ketchup molecules. It is usually caused by evaporation of water or cooling of the ketchup, which causes it to solidify.

The wax melts, it can solidify into a solid again.

It is a physical change because its still milk that hasn't changed state.
