Is sublime a physical change or chemical change?
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.
What is needed for a solid sublime and what change of state occurs?
pressure and the change of state is chemical
What example of changing a substance is an example of what?
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.
What is needed for a solid to sublime and what changes of state occur?

Is dissolution of a solid in a liquid physical or chemical change?
a physical change
What is iodine crystals sublime to make purple gas physical or chemical 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.
What is melting ice a chemical change or physical change?
It is a physical change from a solid to a liquid.
Is changing of a solid to liquid chemical or physical change?
No it is a chemical
Is the change between solid liquid and gas a physical or chemical change?

A piece of solid gold that changes from a solid to a liquid is a physical or chemical change?
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.
Is solid ice melting to a liquid a physical or chemical change?
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 Physical change or Chemical change''?
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.
