The moisture is just water vapor, so you are getting a phase change from liquid to gas. Phase changes are physical changes. For a vaporizer to produce a chemical change it would have to do something drastic like convert the water in to H2 and O2.
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.
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.
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 not a change at all but putting pizza in the oven is a chemical change
An example of a physical reaction is the rusting of iron when exposed to moisture and oxygen in the air. This reaction causes the iron to form iron oxide, a reddish-brown compound known as rust, changing the appearance and properties of the iron.
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.

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.
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.
it is a physical if you can get it back but if you cant it is chemical
Coloring causes only a physical change to icing because it does not alter the chemical characteristics of the icing.
Mixing is a physical process.
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.
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.
