It's a physical change: from solid to liquid, to gas, to plasma.
A physical change.
evaporation
Sublimation is a physical change of state, from solid directly to gas.
The change that occurred to the water is a physical change. In this case, the water changed from a liquid state to a solid state without altering its chemical composition.
Melting a sugar cube is a physical change because the substance undergoes a change in state from solid to liquid without altering its chemical composition.
What kind of energy is involved when the matter changes state?
No, a physical change does not change an object into a different kind of matter. It only alters the form or appearance of the substance, such as size, shape, or state (solid, liquid, gas), without changing its chemical composition.
No, change of state is a physical change.
A change of state is a molecular change.
Melting, freezing, boiling, evaporation are physical change
In changes in which the molecular structure of a substance remains constant, such as changes of state, we often refer to these changes as Physical Changes. If the molecular structure is altered it would be a Chemical Change.
A change in some properties of matter without forming a different kind of matter is called a physical change. This can involve changes in state, shape, size, or appearance of the substance, but the chemical composition remains the same.
