This is a chemical change, a photochemical reaction.
It is a physical change.Density is not a chemical property. Instead, it is a physical property.
Healing a broken bone involves a combination of physical and chemical changes. The bone undergoes physical changes as it reconnects and reforms its structure, while chemical processes occur to help repair and strengthen the bone tissue.
Physical change
Physical change is a change in the structure. Chemical change is a change in the composition. Melting is a physical change. Complexing is a chemical change.
chemical change
No, sunlight speeding up the evaporation of water is not a chemical change. It is a physical process where the water molecules transition from liquid to vapor state without any change in their chemical composition.
This is a chemical change, a photochemical reaction.
It is a physical change because the sun's rays create a physical differential not chemical relates to chemical change ie: the ice tea crystals dissolve in the water. --------- Chemical change, because fading in this case is the result of a photochemical reaction.
A chemical change has taken place. The exposure to sunlight causes the paper to undergo a chemical reaction, breaking down the molecules in the paper and causing the color change to occur.
A physical change
The color of the sky being blue is a physical property, not a physical or chemical change. It is due to the scattering of sunlight by the Earth's atmosphere, particularly by air molecules and small particles in the atmosphere.
Physical change of the paint, not the door.
it is a chemical change
An acid is a chemical compound, not a physical or chemical change.
Yes, drying corn kernels in sunlight is an example of a physical change because it involves a change in the state or appearance of the corn kernels without altering their chemical composition.
It is a physical change.Density is not a chemical property. Instead, it is a physical property.
