False. In a physical change, the substance remains the same even though there may be a change in appearance or state. The molecules of the substance do not rearrange themselves to form a new substance.
Yes, a physical change occurs when matter changes state. This change is reversible and does not alter the chemical composition of the substance. Examples include melting, freezing, vaporization, and condensation.
A physical change of matter is when a substance undergoes a change in its physical appearance or properties without altering its chemical composition. Examples include changes in form, state (solid, liquid, gas), size, or texture. Physical changes are usually reversible.
True. A physical change occurs when matter changes state without altering its chemical composition. In this case, the change from a liquid to a gas involves only changes in physical properties such as volume, shape, and density.
A physical change is different than a chemical change, because in a physical change, the composition of the matter did not change. While in a chemical change, the composition of the matter did change.SO basically, the composition of the matter does not change is the difference between a physical change and a chemical change.yes
In science, phase refers to the physical state of matter, such as solid, liquid, or gas. Phase can also refer to a specific stage in a process or cycle. For example, in biology, phase may describe a stage in the cell cycle.
