Steam melting ice is a physical change. In this process, steam (water vapor) transfers heat to the ice, causing it to change from a solid state to a liquid state without altering its chemical composition. The water molecules remain H2O before and after the change, indicating that no new substances are formed.
What else can I help you with?
Is steam turning to water a chemical or physical change?
The formation of steam is a physical change. The chemical composition of steam (water vapor), is H2O, and the chemical composition of liquid water is H2O, so there is no chemical change going from liquid to gas (vapor/steam). Thus, it is a physical change.
Is steam from a kedal a physica l or chemical change?
The formation of steam from boiling water in a kettle is a physical change. It involves a phase change from liquid to gas without altering the chemical composition of the water molecules.
Is heat changes h20 to steam a chemical change?
physical
When water evaporates into a stream is it a physical change?
Physical change. The chemical formula of the steam still remains as H2O.
Why liquid water changing into steam is a physical not a chemical change?
The steam when cooled changes back to liquid water. A chemical change is usually not so reversible.
A popsicle melting is physical or chemical change?
Melting is a physical change.
Why is boiling or melting a physical change and not a chemical change?
because you dont change the molecule. H2O IS THE SAME MOLECULE as water, ice or steam
Is mixing popcorn steam a physical or chemical change?
it is a chemical change
Is steam a chemical raection?
No. Steam is water vapor. Steam is formed by boiling water, which is a physical change.
Is water is heated and changed to steam a physical change or chemical change?
chemical
Is water evaporating into steam a chemical or physical change?
It is a physical change because the change is reversible.
Is steam turning to water a chemical or physical change?
The formation of steam is a physical change. The chemical composition of steam (water vapor), is H2O, and the chemical composition of liquid water is H2O, so there is no chemical change going from liquid to gas (vapor/steam). Thus, it is a physical change.
When water changes to steam is it a chemical change?
The change of water to steam is a physical change, not a chemical change. In this case, the water molecules are simply changing phase from a liquid to a gas, but the chemical composition of water remains the same.
Is steam from a kedal a physica l or chemical change?
The formation of steam from boiling water in a kettle is a physical change. It involves a phase change from liquid to gas without altering the chemical composition of the water molecules.
When water turns into steam is it a chemical change?
no, physical. The steam can return to water if cooled. Chemical changes are irreversible.
Is heat changes h20 to steam a chemical change?
physical
Is steam condenses on a cold window chemical change?
No, condensation of steam on a cold window is a physical change, not a chemical change. The water vapor in the steam undergoes a change in state from gas to liquid as it loses heat energy to the cold window, but the water molecules themselves remain unchanged.
