Putting icing on a cupcake is a physical change because it does not alter the chemical composition of either the cupcake or the icing. It is simply a change in the physical state or appearance of the cupcake.
Plugging in a plug into a socket is a physical change. The action does not alter the chemical composition of the plug or socket, but only changes their physical state by connecting them electrically.
Putting a penny in lemon juice would cause a chemical change because the lemon juice reacts with the copper in the penny to create copper oxide, which changes the chemical composition of the penny.
it is not a change at all but putting pizza in the oven is a chemical change

Putting ice in a soda to make it cold is a physical change. The ice melts into water, but it does not change the chemical composition of the soda itself.
The humidifier putting moisture into the air is a physical change. It involves adding water vapor, which is a change in the physical state of water from liquid to gas, without altering the chemical composition of the water molecule.
Coloring causes only a physical change to icing because it does not alter the chemical characteristics of the icing.
Plugging in a plug into a socket is a physical change. The action does not alter the chemical composition of the plug or socket, but only changes their physical state by connecting them electrically.
it is a physical if you can get it back but if you cant it is chemical
Putting a penny in lemon juice would cause a chemical change because the lemon juice reacts with the copper in the penny to create copper oxide, which changes the chemical composition of the penny.
Corrosion is a chemical process.
No. The ice melting is a physical change.
It is a physical change because no chemical process is being done, only the fact that it was wet now is dry, a chemical change would be putting salt on ice.
