No, sublimation is a change of state, so it is a physical process.
D. Dry ice subliming is a physical change. Chemically, it's still CO2.
Melting ice is a physical change. It involves a change in state from solid to liquid without altering the chemical composition of the ice.
melting ice a physical change
Nope - ice and water both have the same chemical formula. The only change is with temperature.
No ice melting is a change of state from solid to liquid.
A physical change. It's chemically still CO2, whether solid or a gas.

It is a physical change because even though it is a gas, it can be made back into what it used to be. Just like ice melts into water and water heats and evaporates to gas. Water can easily be frozen back to ice. Gas can turn back to water. Dry ice sublimating is a physical change of carbon dioxide between a solid state and a gaseous state without going through a liquid state. If it were s chemical change, than it would no longer be carbon dioxide after changing state.
Melting ice is a physical change. It involves a change in state from solid to liquid without altering the chemical composition of the ice.
Melting ice is a physical change because it does not change the chemical composition of the water.
its both a chemical change and a physical change.
No. It is a physical change. The chemical formula for water is H2O, and that is also the chemical formula for ice. So there is no chemical change taking place, only a change in the state of matter.
