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.
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. It came from water and is still water.Physical - the water changes from a gas,water vapour, to a liquid, rain.
Clouding is a purely physical process of condensing vaporous water into liquid water (also freezing or sublimating it to solid ice / hail / snow) . Chemically nothing has changed (water molecules stay unchanged, still being water) only there (physical) state (this is a kind of 'condition' of matter) has changed.
When it is iodine (I2) it is only physical sublimation of the black (metallic shiny) I2 crystals into purple heavy gas clouds or fumes
Its a physical change because when clouds form, water vapor condenses into water crystals. That is a phase change which is also a physical change.
because condensation is simply just a change of the water temperature in the air. a temperature change is a physical change. clouds form when the water vapor condenses, so therefore, cloud formation is a physical change.
Precipitation is not a chemical change, but a physical change. The chemical involved is water, and this condenses and cools in the sky to form clouds which become denser and the droplets of water larger until they fall from the sky as rain. The only chemical involved is water.
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.
Water condenses onto aerosols in the air to create clouds.
sulphur dioxide condenses in the clouds, then it falls with the rain. PH 4
Nope. Physical.
