Answer: No, boiling water is a physical change.
Explanation:
Physical change is a change in which there is no rearrangement of atoms and thus no new substance is formed. There is only change in physical state of the substance.
Boiling water is a physical change as liquid changes to gaseous state and no new substance is being formed.
Chemical change is a change in which there is rearrangement of atoms and thus new substance is formed. There may or may not be a change in physical state.

sorry if it’s incorrect! good luck
The water cycle is one interaction between the geosphere and the cryosphere.
Lamps light up by electricity. Although, i'm sure you knew that by now. When a light bulb connects to an electric power supply, an electric current flows between the two metal contacts. As electricity flows between the wires and filament, the filament heats up. The filaments begin to emit photons, which are essentially small packets of light.
Hope this helps!
