Yes. For example, water changing to steam (evaporation) is a physical change. While the water is now a gas (steam) & no longer a liquid, its chemical composition is still the same: H2O (2 atoms of hydrogen & 1 atom of oxygen)

Matter can not change. Its weight always stays the same NO MATTER WHAT, and it can be moved
What is the type of matter change in which matter stays the same and no new substances are formed?

What happens when you change the composition of a mixture and a compound?
What happens is the composition of the compound becomes different and the composition of the mixture stays the same because you can have many types of mixtures.
How do chemicals differ from physical changes?
When matter undergoes a chemical change, the composition of the matter changes. When matter undergoes a physical change, composition of the matter remains the same.
How does expansion and contraction of matter differ from a change in state of matter?
the matter always stays the same, expansion and contraction just means the matter is becoming more/less spread out from one another. A change in the state of matter is turning from solid-liquid-gas. The amount of matter always stays the same!
What stays the same in solids?
Chemical (formula) composition of the compound concerned.
Why is a change in statof matter a phsical change?
A change in state is a physical change because the chemical composition of the substance remains the same.
