Dissolving in water is a physical change.
This is a chemical change.
Combining carbon dioxide and water is a chemical change, not a physical change, but it doesn't make sugar. Carbon dioxide and water makes carbonic acid. CO2 + H2O <--> H2CO3-->H+ + HCO3-
Physical
False. Combining hydrogen and oxygen to form water is a chemical change, not a physical change. During this process, the hydrogen and oxygen atoms chemically react to create new substances, resulting in the formation of water molecules. This transformation involves breaking and forming bonds, which is characteristic of chemical changes.
Boiling water is a physical change because it does not change the chemical composition of the water.
Ocean water is a substance, not a physical or chemical change.
The formation of water from oxygen and hydrogen is a chemical change because new chemical bonds are formed between the atoms to create a new substance with different properties than the original elements.
This is a chemical reaction.
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.
Carving pumpkin physical change or chemical change
Condensation of water is 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.
