No, sublimation is a change of state, so it is a physical process.
Sublimation is only physical, same like condensation and evaporation.
No. Sublimation is a physical change.
D. Dry ice subliming is a physical change. Chemically, it's still CO2.
melting ice a physical change
melting ice a physical change
Nope - ice and water both have the same chemical formula. The only change is with temperature.
It is a physical change. It is still the same substance.
A physical change. It's chemically still CO2, whether solid or a gas.

Subliming (better known as sublimation) is a change in state, so it is a physical change.
melting ice a physical change
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.
