no
ice melting is a physical reaction
No, melting of lead is a physical change, not a chemical reaction. A chemical reaction involves the breaking and forming of chemical bonds to create new substances, while melting only involves a change in state from solid to liquid with no change in chemical composition.
No.
no- melting is not a chemical change. It is merely a change in state of the same substance not a chemical reaction.
No, it is a physical change, not a chemical reaction.
it is certainly not a chemical reaction, and it is still melting something, so it is a physical reaction. it does depend HOW you melt it, but other than that, it is a physical reaction.
Ice melting is a physical reaction, not a chemical one. It involves a phase change from solid to liquid as the temperature of ice increases above its melting point without any change in the chemical composition of the water molecules.
Because melting sugar turns color to form caramel. i.e. it has changed and specifically it has undergone a CHEMICAL CHANGE (Or chemical reaction). When melting ice, no chemical reaction occurs, and so it is just a PHYSICAL CHANGE.
Melting of ice with salt is example of physical change as there is no chemical reaction involved .
A melting candle is an example of a physical change, not a chemical reaction. The process involves a solid candle turning into liquid wax due to the application of heat, with no change in the chemical composition of the wax molecules.
yes because it turns into water
not it can always be changed back to its original shape. but if you burn metal which i dont consider doing it is a chemical change. like melting butter and burning butter. burning is chemical, melting can be cooled again into its original form.
