Is water being split to form two new substances hydrogen and oxygen a change of state?
No, the process of water being split into hydrogen and oxygen is a chemical change, not a change of state. During this process, new substances are formed through a chemical reaction, rather than a change in the physical state of the water molecules.
When atoms combine is it a physical change or a chemical change?
When atoms combine to form molecules, it is a chemical change. In a chemical change, new substances are formed with different properties from the original substances. This is in contrast to physical changes, where the state or appearance of a substance may change without forming new substances.
What happens to substances as they lose or gain energy?
As substances lose energy, they tend to decrease in temperature and may change state (e.g. solid to liquid). Conversely, as substances gain energy, they tend to increase in temperature and may change state in the opposite direction (e.g. liquid to gas).
Are state changes physical or chemical changes?
State changes are physical changes because they involve a change in the physical properties of a substance, such as its form or state of matter (solid, liquid, gas). No new substances are formed during a state change, making it a physical change rather than a chemical change.
What is the difference between a chemical change and a change of state?
A chemical change involves a rearrangement of atoms to form new substances with different chemical properties, while a change of state is a physical change where a substance transitions between its solid, liquid, or gas state without changing its chemical composition.
What does change of state operation?
Change of state is a property that involves the substances of chemical and physical changes
Is water being split to form two new substances hydrogen and oxygen a change of state?
No, the process of water being split into hydrogen and oxygen is a chemical change, not a change of state. During this process, new substances are formed through a chemical reaction, rather than a change in the physical state of the water molecules.
Why does the way water change from one state to another compare to the way other substances change?

Can substances that have undergone a physical change be changed back to their original state?
Yes
What kinds of changes in substances are always physical change?
The kinds of changes in substances that are always physical changes are changes in the state. This is the change from solid, to liquid and then to gas and the reverse.
When atoms combine is it a physical change or a chemical change?
When atoms combine to form molecules, it is a chemical change. In a chemical change, new substances are formed with different properties from the original substances. This is in contrast to physical changes, where the state or appearance of a substance may change without forming new substances.
Do acids melt substances?
No, melting is a change of state caused by heat. Acids are corrosives.
Adding or removing what makes substances change from one state to another?
A change of state is when a substance shifts from solid, liquid or gas to another state. This happens when heat is removed or added.
What happens to substances as they lose or gain energy?
As substances lose energy, they tend to decrease in temperature and may change state (e.g. solid to liquid). Conversely, as substances gain energy, they tend to increase in temperature and may change state in the opposite direction (e.g. liquid to gas).
Most substances change their physical state and?
Most substances change their physical state and transition from solid, to liquid, to gas when heated or cooled. This phase transition occurs due to changes in the arrangement and movement of the particles within the substance.
Do all substances behave like water when they change from the solid state to the liquid state?
No, not all substances behave like water when they change from the solid state to the liquid state. The behavior of a substance during phase changes depends on its molecular structure and the forces between its molecules. Water is unique in that it expands when it freezes, whereas most substances contract when they solidify.
Are state changes physical or chemical changes?
State changes are physical changes because they involve a change in the physical properties of a substance, such as its form or state of matter (solid, liquid, gas). No new substances are formed during a state change, making it a physical change rather than a chemical change.
