What is the difference between boiling water and decomposing water?
Boiling water is the process in which water reaches its boiling point and turns into vapor, while decomposing water involves breaking down water molecules (H2O) into its constituent elements, hydrogen and oxygen. Boiling water is a physical change, while decomposing water is a chemical change. Boiling water is reversible, while decomposing water is typically irreversible.
Is decomposing water by passing an electric current through it a chemical or physical change?
Decomposing water by passing an electric current through it is a chemical change because it involves the breaking of the chemical bonds in water molecules (H2O) to form hydrogen gas (H2) and oxygen gas (O2). This reaction results in the formation of new substances with different chemical properties.
Is it a physical change chemical change when salt dissolves in water?
Physical
Is boliling water a chemical or physical change?
Boiling water is a physical change because it does not change the chemical composition of the water.
Is ocen water a physical or chemical change?
Ocean water is a substance, not a physical or chemical change.
Is hydrogen burning a physical or chemical change?
The burning of hydrogen is a chemical change because it involves the rearrangement of the atoms in the hydrogen molecule to form water. This process also releases energy in the form of heat and light.
Is spilling water a chemical change?
No, spilling water is a physical change, not a chemical change. A chemical change involves a change in the chemical composition of a substance, whereas spilling water only changes its location and physical state.

4. decomposing of water explanation: a chemical change is when you chemically change a substance, and a new one is formed
Is condesning water a chemical or physical change?
Condensation of water is a physical change.
If water is boiling is it a chemical change or a physical change?
It is a physical change. All phase changes are physical, not chemical. The chemical composition of water does not change when it changes from a liquid to a gas, or for that matter, to a solid.
Can heating water to change it to water vapor be a chemical change?
No, this is definitely a physical change, absolutely not a chemical.
