Chemical Change
chemical change
A new substance is formed only after a chemical change.
A physical change is when a substance changes, but still keeps its identity. When a chemical change occurs, the substance changes its identity.

it is called a meniscusal form
A chemical change occurs when a new substance is formed with different properties from the original substance. This change involves the rearrangement of atoms and the formation of new chemical bonds. It is typically irreversible.
Of course not. It is a physical change. A chemical change occurs when the identity of a substance changes.
A phase change occurs. This can involve transitions between solid, liquid, and gas states, such as melting, freezing, evaporation, condensation, sublimation, and deposition. During these changes, the particles of the substance reorganize themselves into a different arrangement.
When a substance reaches its melting point it changes from solid to liquid. When a substance reaches its boiling point it changes from liquid to gas.
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.
The phase change in which a substance changes from a gas to a liquid is called condensation. This occurs when the gas loses energy, typically through cooling, and transitions to a liquid state.
A physical change occurs when a substance changes its physical form or state without changing its chemical composition. Examples include changes in size, shape, or state of matter (solid, liquid, gas).
