Change of state is always physical.
You have not lost or gained any atoms. Therefore its physical.
Sublime is a physical change because it involves a substance changing from a solid directly to a gas without going through a liquid phase. This process is reversible, and the chemical composition of the substance remains the same.
pressure and the change of state is chemical
iodine'(solid) can sublime to gas. also so does camphor Sublimation is a physical change, not a chemical change. Any substance that burns demonstrates a chemical change called combustion.

a physical change
The sublimation of iodine crystals to produce purple gas is a physical change. This is because the change in state from solid to gas does not involve a change in the chemical composition of the substance. The purple color of the gas is due to the absorption and emission of specific wavelengths of light by the iodine atoms.
It is a physical change from a solid to a liquid.
No it is a chemical
Physical
The change from solid gold to liquid gold is a physical change because it does not alter the chemical composition of the gold. The transition from solid to liquid is a result of a change in temperature and does not involve any chemical reactions.
Melting solid ice into liquid water is a physical change. It involves a phase change from solid to liquid without altering the chemical composition of water molecules.
is dissolving a chemical or physical changeWell, it is not. Because you are not changing the chemical identity of the solid. It's still solid chemically and water chemically.
