Physical because no reaction is taking place.
Original answer is INCORRECT. Clouds forming in the sky is a physical change because a chemical change requires a change in the chemical composition of a material and the H2O, no matter a solid liquid or gas, is always H20.
Chemical The acid in the lemon clouds the water and the elements combine.
This is a physical change. When water vapor in the air condenses to form clouds, it is a change in state from a gas (water vapor) to a liquid (water droplets). No new substances are formed.
It is a physical change, because you are not making a new substance.The water is still staying water, and it is reversible, because if it is making clouds, the clouds become rain, and the rain can then evaporate or the clouds themselves can evaporate.
A physical change
Clouds are formed by water vapors condensations. And the processes implied in the formation of clouds (evaporation, condensation, freezing) are all change of matter - physical changes. A chemical process need a change in the nature of the chemical reactants - but in this case the chemical formula of water (H2O) remain the same.
Physical change of the paint, not the door.
Hail formation is a physical change. It involves the freezing of water droplets in clouds into ice pellets, which then fall to the ground. This process does not involve a chemical change in the composition of the water molecules.
it is a chemical change
Crushing charcoal into powder is a physical change, as it alters the size and shape of the charcoal without changing its chemical composition.
An acid is a chemical compound, not a physical or chemical change.
It is a physical change.Density is not a chemical property. Instead, it is a physical property.
